Echoes of Doubt. The Impostor Phenomenon as an Internalized Barrier for Educational Advancement
Authors: Jansen Max P.
Published: January 2025

The Impostor Phenomenon (IP) represents a popular research topic among scholars in various disciplines, frequently approached through a lens of individualization and pathologization. This study explores its relevance within the educational domain and contextualizes the IP by examining its association with social group membership along the dimensions of gender, immigration origin, and socioeconomic status. Providing empirical insights into the implications of the IP for social upward mobility through educational gains, this study addresses two research questions: (1) “who is particularly affected by the IP?” and (2) “is the IP negatively associated with educational efficacy beliefs and educational aspirations?”. To investigate these questions, the study applies a sociological framework for understanding the IP from a lens of social theory and examines its social stratification drawing on data from a register-based data collection among German adolescents aged 15-18 (n=4,697). The results of linear regression and probability models for three dependent variables show that (1) the IP is positively associated with disadvantaged social group membership, whereas it is negatively associated with two drivers for educational upward mobility, namely (2) educational efficacy beliefs and (3) educational aspirations. These findings suggest that the IP can undermine opportunities for social upward mobility by reinforcing internalized notions of inadequacy and not belonging to higher educational spheres. As individuals from disadvantaged social groups are more susceptible to the IP, which is associated with lower confidence in educational abilities and reduced pursuit of higher education, the IP appears to constitute an internalized barrier to upward social mobility. These results highlight the societal role of the IP, emphasize the value of understanding it from a sociological perspective, and demonstrate the importance of analyzing it through a lens of social stratification, both within and beyond the educational domain.

Published: January 2025

This study investigated self-reported language proficiency, attitudes, and perceptions across generations to assess the current state of Hawaiian language reclamation. Drawing on survey responses from 177 individuals living across the Hawaiian Islands, results shared trends in proficiency, school experiences, and motivations for learning Hawaiian. Survey responses revealed that self-reported proficiency across all language domains was higher with younger generations, with Millennials and Generation Z demonstrating higher levels of proficiency. Respondents consistently identified Kaiapuni schools (i.e., Hawaiian-medium schools) as the strongest contributors to language reclamation, highlighting their role in fostering proficiency and cultural identity. This study underscores the importance of immersion education, community support, and sustained investment in teacher recruitment and training for advancing language reclamation. Findings offer critical lessons for Indigenous language revitalization globally, emphasizing the interplay between intergenerational engagement, educational opportunities, and shifting language attitudes.

Authors: Maria Dolores Gómez Barriga
Published: January 2025

Background/Aim:

Acute Coronary Syndrome (ACS) remains a significant cause of morbidity and mortality worldwide. Cardiovascular disease (CVD) prevention remains crucial despite advancements in clinical outcomes. Empowering patients with self-care skills is essential for managing ACS, and digital tools can enhance these practices. This study qualitatively evaluates patients' experiences with post-ACS digital tools to improve self-care.

Material and methods:

A qualitative phenomenological approach was employed, utilizing in-depth interviews with patients diagnosed with ACS enrolled in a telephonic follow-up program. Sampling continued until saturation was reached. Data collection included patients' perceptions of the accessibility and utility of digital tools in enhancing self-care knowledge. A descriptive analysis of age and gender was conducted to analyze potential demographic influences.

Results:

Ninety patients participated, with males predominating (70%) and a mean age of 69.2 years. Patients reported positive engagement with both educational videos and health blogs. Preferences varied, with 54% favoring videos and 36% preferring blogs. Difficulties in accessing digital tools were observed, especially among elderly patients. However, patients emphasized the instrumental role of these tools in complementing knowledge and facilitating self-care, while recognizing the irreplaceable value of direct interaction with healthcare professionals.

Conclusions:

Future interventions should focus on improving digital tools accessibility and effectively integrating them into patient care pathways to optimize self-care outcomes.

Authors: Ngaide Aliou Alassane
Published: January 2025

Introduction: The objectives of this study were to determine the frequency of tuberculous pericarditis and to describe its diagnostic, therapeutic, and prognostic aspects.

Methodology: We conducted a retrospective descriptive and analytical study over five years from January 1, 2015, to December 31, 2019, at the General Hospital Idrissa POUYE in Dakar. The study focused on patients aged over 18 years who were hospitalized for tuberculous pericarditis, with or without effusion, and treated with antituberculous drugs according to the protocol established by the National Tuberculosis Control Program (PNLT) of Senegal. This work was carried out in collaboration with the hospital management after obtaining approval from the cardiology department by signing the access form to patient records. Data were entered using Sphinx software version 5.1.0.2 and analyzed with SPSS (Statistical Package for Social Sciences) software version 18.

Results: We identified 108 cases of pericarditis from all causes, representing a hospital prevalence of 1.95%. Among these, 42 were of tuberculous origin, with a hospital prevalence of 0.76% and 38.89% of all pericarditis cases, with a male predominance (sex ratio of 1.33). The mean age was 28.6 ± 10 years, with a predominance in the 20-29 age group (57.1%). More than half of the patients (57.1%) had a low socio-economic status, and 42.85% had a history of contact with tuberculosis. Symptoms were mainly dyspnea and chest pain (78.57% each). Tachycardia (85.7%) and pericardial friction rub (42.9%) were frequently observed. The pericardial puncture fluid was sero-hematic in 66.7%, and the study showed a positive Rivalta test with lymphocytic predominance. The adenosine deaminase (ADA) level in the pericardial puncture fluid, performed in 12.5% of patients, was positive. HIV serology was positive in 10% of cases. Cardiac ultrasound showed effusion in all patients, with a large amount in 64.29% of cases. All patients received antituberculous treatment, with 35.7% also receiving corticosteroids. The average hospital stay was 11 days, with complication rates of pericardial constriction (14.3%) and deaths (7.1%).

Conclusion: Tuberculous pericarditis remains a significant health issue, particularly among patients of low socio-economic status and those with a history of contact with tuberculosis. Despite the availability of treatments, complication and mortality rates remain considerable, highlighting the need for early diagnosis and comprehensive management.
Evaluation of the Antioxidant Properties of Coumarin Derivatives Using Spectroscopic Methods
Authors: Gümüş Hacer
Published: January 2025

Coumarin derivatives are perceived as part of defense mechanisms in plants due to their commonly observed antimicrobial, antioxidant, antitumor, anti-inflammatory, and other biological activities. Investigating the molecular structure of coumarin derivatives using computational programs like Gaussian is an effective method for understanding the biological, chemical, and physical properties of these compounds. Therefore, in this study, the molecular structure parameters and spectroscopic (IR, NMR) properties of our coumarin derivative compound were theoretically examined using the DFT method with the B3LYP/LanL2MB basis set. This investigation is crucial for understanding the biological activities of coumarin derivative compounds, obtaining clues for new drug design, and elucidating reaction mechanisms.

Intraoperative Findings Heterotopic Ossification of the Mesentery. Case Report and Literature Review
Authors: José Alejandro Díaz-Castillo
Published: January 2025

Introduction: Heterotopic ossification of the mesentery is a rare condition in which there is bone formation in tissues that normally do not ossify. In the field of general surgery, it is common to encounter this intraoperative finding incidentally. The etiological and pathophysiological mechanism that leads to overstimulation of osteoblastic activity has not yet been established.

Clinical Case: We present a case of a 41-year-old patient with a surgical history of perforated appendicitis one year ago, who required right hemicolectomy + colostomy, was admitted for colostomy closure with intraoperative findings of multisegmental bony mass.

Discussion: According to the literature, the incidence of heterotopic ossification of the mesentery is unknown and it is associated with a wide age range. Despite its association with surgical history, which generally induces a proinflammatory state in the mesentery, leading to the formation of ectopic bone tissue, the surgical indications are currently mainly secondary causes such as peritonitis, and therefore, these findings are usually incidental intraoperative discoveries, as in the presented case report.

Conclusion: heterotopic ossification of the mesentery is a rare condition that involves an inflammatory process where the presence of osteoblasts is described by theories. It often poses a challenge for the surgeon, considering that it is associated with an incidental intraoperative finding.
Epidemiology of Agranulocytosis and other Medically Important Adverse Reactions in Mexican Population Associated with Metamizole
Authors: -González Leonel Gonzalez
Published: January 2025

Background/Aim: Metamizole, a non-opioid analgesic, has been used for a long time, but studies linking it to potentially life-threatening adverse drug reactions, such as agranulocytosis, have raised safety concerns. However, the reported incidence of these events is widely variable. This study aims to shed light on the pharmacological safety of metamizole in Mexico, with a particular focus on medically important suspected adverse drug reactions, especially agranulocytosis.

Materials and Methods: We extracted data on cases of medically important suspected adverse drug reactions (SADRs) and prescriptions for metamizole and non-steroidal anti-inflammatory drugs (NSAIDs) from the database of medical emergency records within the Mexican Ministry of Health, covering the period from 2014 to 2022. We calculated frequencies, proportions, and reported odds ratios for medically important SADRs and agranulocytosis.

Results: Metamizole ranked as the third most frequently prescribed non-opioid analgesic and accounted for 13.7% of medically important SADRs potentially linked to drugs of its class. Among consultations involving metamizole prescriptions, the most common SADRs included unspecified kidney and ureter disorders, toxic liver disease, other specified forms of angina pectoris, aplastic anemia, and agranulocytosis, the latter being recorded in just 0.002% of these consultations. The reported odds ratio for agranulocytosis associated with metamizole prescription compared to NSAIDs was 0.3 (95% CI 0.20 - 0.45).

Conclusions: The data source we analyzed provides limited evidence regarding the safety profile of metamizole, as it did not allow us to establish a causal relationship between drug prescription and SADRs. Our findings suggest that metamizole is widely used in Mexico and that adverse reactions associated with its prescription may occur less frequently than those linked to NSAIDs. Additionally, metamizole-induced agranulocytosis appears to be rare in the Mexican context.
Model of high-strength lightweight concrete
Authors: Inozemtcev A. S. , Korolev E. V.
Published: January 2025

Modeling is a tool of scientific cognition that makes it possible, by replacing the object under study with its representation (model), to explore it and interpret the results on the object itself. Obviously, the material model should allow for the study of the influence of prescription factors on its properties (direct task) or, with established requirements for the material, determine the parameters of the model (values of factors) that ensure the achievement of established requirements (inverse task). In the course of the study, a compounding and structural model of high-strength lightweight concrete was developed, which is a system of equations that establish the relationship of structural parameters (geometric characteristics, compounding factors (component content) with the sedimentation rate and viscosity of the concrete mixture and the specific strength of concrete. The conducted modeling makes it possible to predict the properties of the concrete mixture and concrete on a hollow aggregate and establish boundary conditions to achieve the target values of key quality indicators. It has been established that an urgent task in the production of high-strength lightweight concretes is the development of compounding and technical solutions that provide a combination of high mobility and uniformity, which is explained by the value of I/C as a key control factor located in opposite optimization areas, and in order to achieve high specific strength of high-strength lightweight concrete, it is additionally necessary to regulate the adhesion of cement stone to a hollow filler.

Published: January 2025

OBJECTIVE

The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture.

METHODS

Implementation of 3D CT–guided radiofrequency therapy of the GG with and without use of 3D PPM was analyzed. The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.

RESULTS

Pain severity reduction was equivalent in both groups, and postoperative facial numbness was not observed. A statistically significant difference in radiation exposure parameters was revealed: radiation time was 181.67 ± 2.99 and 310.50 ± 18.46 seconds (p < 0.001); dose area product was 950.97 ± 115.41 and 1545.48 ± 135.04 µGy*m2 (p < 0.005); and the air kerma reference point was 114.53 ± 16.81 and 190.88 ± 17.48 mGy (p < 0.005) in groups 1 and 2, respectively. The severity of pain during a puncture needle insertion was assessed as mild in 62.5% and 25%, moderate in 37.5% and 41.6%, and severe in 0% and 33.3% of patients in groups 1 and 2, respectively. No serious perioperative complications were observed.

CONCLUSIONS

The use of 3D PPM allows for controlled needle insertion, reducing the radiation dose to the patient and medical staff, reducing pain during a puncture needle insertion into the area of the foramen ovale, and minimizing the risk of postoperative complications.

Published: January 2025

The Nibung (Oncosperma tigillarium (Jack) Ridl.) is a plant that serves as the floral mascot of Riau and symbolizes the spirit of unity and brotherhood among its people. Genetic diversity research is essential for the conservation of this species, with DNA extraction being a critical initial step. This study compared three types of buffers: CTAB, Alkyl Benzene Sulfonate (ABS) surfactant detergent, and Sodium Laureth Sulfate (SLS) surfactant detergent. The aim of this research was to identify alternative buffers to replace CTAB and simplify the extraction of genomic DNA from Nibung. Parameters measured included the presence of DNA and DNA concentration, using electrophoresis and a nanodrop spectrophotometer. The results showed that clear genomic DNA bands were successfully obtained for 24 Nibung accessions, with only two accessions, Nibung2s and Nibung6s, showing smeared bands when using the SLS surfactant detergent buffer. The genomic DNA concentrations ranged from 526.2 to 3,829.2 ng/µl. These concentrations are suitable for use as DNA templates in further research. Thus, both ABS and SLS surfactant detergent buffers can be considered viable alternatives to CTAB for extracting genomic DNA from Nibung.

Makrosoziale Aspekte internationaler Jugendarbeit
Authors: Dimbath Oliver , Ernst-Heidenreich Michael
Published: January 2025

Oliver Dimbath und Michael Ernst-Heidenreich setzen sich mit makrosozialen Aspekten Internationaler Jugendarbeit auseinander. Diese werde bislang – besonders unter dem Einfluss pädagogischer und psychologischer Sichtweisen – hauptsächlich aus mikrosoziologischer Perspektive betrachtet, stellen die beiden Forscher fest. In den Blick kämen so soziale Nahbeziehungen und Interaktionsordnungen in kleinen Gruppen sowie die Lern- oder Entwicklungschancen des Subjekts. Programmatisch sei die Internationale Jugendarbeit allerdings auf makrosoziale Ziele (gesamtgesellschaftliche Ziele oder Ziele von Staaten) ausgerichtet. Die Ziele, die für dieses Praxisfeld vorgegeben sind, und die wissenschaftliche Forschung, passten also strukturell bislang kaum zusammen. Deshalb entwickeln die Autoren eine Systematik zur makrosoziologischen Analyse Internationaler Jugendarbeit und definieren sie z.B. als ein Verfahren, relevante Grenzen zwischen Räumen aufzulösen oder neue Sichtweisen jenseits gesellschaftlicher Traditionen zu entwickeln. Die Wirkungsdimensionen dieses zivilgesellschaftlichen Tätigkeitsfeldes werden also in einer anderen Perspektive als der bisherigen angegangen. Abschließend geben die Autoren einen Ausblick auf den möglichen Nutzen einer solchen Betrachtungsweise.

Privatization The Implementation Of Electronic-Based Law Enforcement Responsibility In The Police Traffic Corps Of The Republic Of Indonesia
Authors: Suryanto Adi , Adhitia Samlibry
Published: January 2025

The topic of privatization rarely appeared dominantly in the implementation of activities controlled by the police in Indonesia before. However, in other countries in the last two decades, the wave of privatization has been inevitable due to the increasing number of government, military and police activities that cannot be carried out on their own, especially in matters that occur after the procurement of special equipment, such as maintenance and matters related to the operation of the equipment. itself. This condition occurs due to the incompetence of personnel and is supported by the inability of a timely budget with planning activities. Therefore, public participation in cooperation in traffic law enforcement (Public Private Partnerships in Traffic Enforcement), especially in the context of public transparency and more open communication, is very important in order to lead to success and sustainable implementation of all activities of the Indonesian National Police, especially in Traffic Corps. This paper is expected to be able to identify the need for such a business model in the future to make a policy making easier.

Published: January 2025

Interfaith marriage in Semarang has become a controversial issue, challenging established religious, cultural, and legal norms. The study aims to address two key questions on how Indonesian society responds to interfaith marriage and what role does the Qur'an play in the interfaith marriage controversy in Semarang. Through this study, we seek to gain an in-depth understanding of the interaction between religious teachings and social responses, with the broader aim of enhancing insights into the influence of Qur'anic exegesis on interfaith marriage dynamics. Th study adopts a qualitative approach, utilising document analysis and in-depth interviews. Primary participants include interfaith couples and Indonesian netizens. Data collection is conducted through interviews, field observations, and document analysis, including Qur'anic exegesis, religious decrees, fatwas, and public commentary. Thematic analysis is applied to identify evolving patterns in Islamic legal understanding and its impact on social harmony. In Semarang, interfaith marriage has proved to be a contentious affair for both social and legal researchers owing to some of the intricate issues it entails. Interfaith couples often experience disapproval not only from their families but society as a whole. A considerable part of society shows contempt, as per the religious views such marriages can endanger the family’s spirituality. Nevertheless, there are some who advocate for Indonesian multiculturalism and the values of respect and social harmony thus viewing interfaith marriages as legitimate. This dispute includes discussions of Qur’anic interpretation and Islamic law as they assert different viewpoints regarding the legitimacy of marriage of Muslims with Ahl al-Kitab. What aggravates the situation along with the ambiguous national legislation is the fatwa that was promulgated by Majelis Ulama Indonesia about interfaith marriages. This paper responds to the identified problems by offering some recommendations for communication, better understanding around the differences as well as the maqasid al-shari’ah objectives of protecting religion and nashab.
A method introducing deteriorating bond at the interfaces and declining load transfer at the joints in the existing design methods for concrete pavements
Authors: Van Cauwelaert Frans , Jasienski André
Published: January 2025

Most of the concrete highways of the Belgian road system have a structure composed of a CRCP surface layer, a thin intermediate asphalt bond layer and a lean concrete base layer on one or more granular sub bases. They are designed as an equivalent composite rigid layer on an elastic granular sub grade. The equivalent Young’s modulus of the composite layer is assumed to be equal to the modulus of the concrete surface layer, the thickness is assumed to be equal to the sum of the thickness of the three layers; the equivalent moment of inertia and the equivalent stiffness depend on the values of the thickness and the moduli of each layer and the bond conditions between the layers. Several investigations regularly performed on pavements currently thirty years old have shown a systemic deterioration of the bond between the surface layers and of the load transfer at the cracks of the CRCP or at the joints of concrete slabs. In this paper we present a mathematical model that permits the computation of the influence of this systemic deterioration on the lifetime of the pavements.
A Review and Discussion of Current Developments Involving Bonded Concrete Overlays of Airfield Pavements
Authors: Semen Peter M. , Rollings Raymond S.
Published: January 2025

Fully-bonded portland cement concrete overlays have been widely used by the U.S. military to rehabilitate rigid airfield pavements that have functional deficiencies – such as roughness, surface profile, poor friction, or foreign object damage (FOD) potential. Significant developments in the concrete industry over the last 15 years – including considerable changes in concrete material additives, construction practices, surface preparation, and computer modeling – have led to changes in traditional practices. A survey of the recent literature in relevant topics led to the synthesis of applicable developments from several areas. New research on failure mechanisms, surface preparation, bonding agent use, and interface texture has provided fresh insight regarding some conventionally-accepted wisdom. Integrating contemporary findings into recommended practice should improve the oft-times variable nature of achieving the best bonding conditions for bonded overlays and ultimately improve their reliable long-term performance.
ALTERNATIVE DOWEL BARS FOR LOAD TRANSFER IN JOINTED CONCRETE PAVEMENTS
Authors: Larson Roger M. , Smith Kurt D.
Published: January 2025

Concerns over the long-term effectiveness of epoxy coatings of dowel bars have motivated some agencies to investigate the use of alternative dowel bar materials. Alternative dowel bars are either constructed of a non-corrodible material or contain a non-corrodible cladding for protection against corrosion. The need for a long-lasting dowel bar design has become even more acute as many highway agencies are exploring the development of long-life portland cement concrete (PCC) pavements, ones that are capable of providing service lives of 40, 50, or even 60 years. Under Test and Evaluation Project 30 (TE-30), High Performance Concrete Pavements (HPCP), the Federal Highway Administration (FHWA) is exploring the applicability of innovative PCC pavement design and construction concepts, including the use of alternative dowel bars. Several projects incorporating alternative dowel bars have been constructed under that program, and interest in these projects is high. At the same time, the Highway Innovative Technology Evaluation Center (HITEC) is sponsoring an evaluation the HPCP projects that specifically compare the performance of 38-mm (1.5-in) diameter fiber reinforced polymer (FRP) composite or Type 304 solid or concrete-filled tubes to standard epoxy-coated steel dowels. This paper summarizes some of the types of alternative dowel bars currently available for use in jointed concrete pavement (JCP) construction, describes some of their advantages and disadvantages, and reviews some of the recent field projects constructed under the TE-30 or related programs that incorporate alternative dowel bars. In addition, a brief summary of related laboratory or accelerated pavement testing on alternative dowel bars is provided. Recommendations for additional research and field testing are also presented.
Concrete Pavement Performance and Research at the Minnesota Road Research Project – The First Ten Years
Authors: Burnham Thomas
Published: January 2025

The Minnesota Road Research (MnROAD) facility was constructed in the early 1990’s to include fourteen plain jointed concrete pavement test sections. Nine of the test sections are interstate highway designs with design lives of 5 or 10 years. The other five test sections are low-volume road designs. With traffic loading beginning in 1994, the test sections have now experienced over 10 years of load and environmental effects. During that time, a tremendous amount of data collection and research analysis has taken place. The condition and ride performance of the concrete pavement test sections is characterized. Significant findings from selected studies are presented. The performance of the 5-year and 10-year design test cells shows that Mn/DOT’s current concrete pavement design method needs significant improvement. The lessons learned from the operation of the MnROAD project can be used to improve the next generation of concrete pavement design methods and test facilities.

Published: January 2025

The section of prestressed/post tensioned pavement was constructed in the spring of 2004, in conjunction with reconstruction of a section of I-10 in the Los Angeles, CA area. While this technology has been used in the past, significant progress is being made in terms of practical application. The paper includes a discussion of concepts pertinent to this type of pavement as well as fabrication and construction details for delivery of the pavement. This project utilized a specific geometric design so that the shoulder is included in the prestressed panels. Details of the fabrication process of the panels and field assembly are discussed. The paper describes details of panel fabrication and handling. It also addresses placement of the panels and the post tensioning operations. The details include those for jointing and post tensioning of slabs. Advantages of this type of pavement construction include reduced field construction time and long anticipate service life. The nature of this pavement design makes it an excellent form of long-life pavement. The significance of this research is the demonstration of successful application of precast post tension technology for pavement repair and construction.
Design of Heavily Loaded Continuously Reinforced Concrete Pavements
Authors: Silfwerbrand Johan
Published: January 2025

Industrial pavements are subjected to very large loads, e.g., axle loads exceeding 1000 kN and containers stacked in height and blocks equaling single loads of even higher magnitude. Often, industrial pavements are located in harbors where the subgrade may consist of the previous bottom of the sea and fillings. It is necessary to make the concrete pavement competitive and as thin as possible without jeopardizing safety. Continuous reinforced concrete pavements (CRCP) may be one possibility. Prof. A. Losberg used yield line theory (YLT) for the design of CRCP. The YLT is described in the paper through some simple and practical cases. The YLT allows considerably higher ultimate loads than the theory of elasticity. One problem is how to handle fatigue. It is illustrated by tests found in the literature. Finally, a new Swedish design concept for industrial CRCP based on YLT and containing a high safety factor to prevent fatigue failure is described.
Evaluation of PCC Joint Stiffnesses Using LTPP Data

Shear stiffness of joints and cracks profoundly affects the performance of concrete pavements. This paper presents a systematic analysis of stiffnesses of joints in jointed concrete pavements (JCP) and cracks of continuously reinforced pavements (CRCP) using deflection data collected under the Long Term Pavement Performance (LTPP) program. To estimate joint behavior, representative load transfer efficiency (LTE) indexes were calculated for all LTPP sections and a trend analysis was performed to evaluate the effect of Falling Weight Deflectometer (FWD) load level on LTE. It was found that the majority of the joints did not show significant load-level dependency. This justifies use of a simple Tabatabae-Barenberg (TB) model for routine pavement analysis. The paper also discusses a backcalculation procedure for determination of TB model parameters. Joint stiffnesses were backcalculated from LTEs, coefficients of subgrade reactions, and radii of relative stiffness. As expected, it was found that cracks in CRCP usually have higher stiffnesses than joints of JCP, while non-doweled joints usually have much lower stiffness than doweled joints. It was also found that joint stiffness could vary significantly during the day.

Published: January 2025

An investigation has been performed into a treatment of the surface of ground granulated blast furnace slag (GGBFS) cement concrete in order to improve the frost salt scaling resistance. A sodium monofluorophosphate (Na- MFP) solution has been applied. The results show that the resistance is substantially improved. The microstructural characteristics are also discussed. In addition, the effect of various percentages of Na-MFP solution on frost salt scaling resistance of GGBFS mortar phase is presented. It is concluded that the Na-MFP treatment modifies the carbonate phases and improves the early resistance of the GGBFS cement matrix with water to cement ratio of 0.45 against frost salt scaling attack.
Hydration Modulation Measures to Mitigate the Negative Effects of Paving Concrete in Hot Weather

Published: January 2025

Concrete Placement above a temperature of 35°C (95°F) is typically prohibited in many specifications for construction due to concerns over early-aged cracking, early stiffening, increasing setting temperature, and reduction of ultimate concrete strength etc. A common way to control or modulate the concrete placement temperature has been to cool the concrete constituents (e.g., aggregates and water) or the concrete mixture by using ice or injecting liquid nitrogen. However, these temperature modulation measures often increase the cost of the concrete. In the present study, an attempt has been made through laboratory testing to investigate the effect of hydration modulation measures such as modifying mixture proportions in terms of fly ash proportions in order to combat the negative effect of high temperature placement. Use of fly ash contents greater than 25-30% is an affective way to control the high heat generation and excessive drying shrinkage that is characteristic of high placement temperature and can mitigate the negative effect of high set temperature gradients that can result from placing artificially-cooled concrete under hot weather conditions.

Authors: Bury Mark A. , Nmai Charles
Published: January 2025

Recent developments in admixture technology can dramatically modify and control both the rheological and hardened properties of concrete. Using the right combination of specific admixtures and appropriate mixture proportions are the first steps towards producing concrete with the desired performance attributes. For example, a system of innovative admixtures can now produce a novel concrete mix that facilitates the rapid repair of concrete pavements that permits opening to traffic within just 4 hours after concrete placement. This paper provides a description of the concrete system and its components, includes test data, and contains a review of successful projects, and demonstrations for local and national transportation agencies.

Published: January 2025

During the last decades there were no official national standards for the design of concrete pavements for highways and streets in Brazil. Due to technical differences between each region, it is necessary to develop consistent research to establish design tools for pavements. Researches carried out last five years could immediately be used to assure highway officials that both rupture criteria and climate-traffic effect models for concrete slabs are reliable and sound for a specific project condition. This paper presents the calibration of stress equations for the design of concrete slabs based on field measurements, models for defining thermal differentials for tropical conditions, and the main results for calibration of a fatigue model for concrete, all in an attempt to determine appropriate rules for the local design of concrete pavements.
Joint design and joint performance of Plain Concrete Pavements (JPCP) - Investigations and experiences in Germany -
Authors: Lechner Bernhard
Published: January 2025

Unreinforced concrete pavements have to be equipped with longitudinal and transversal kerbs to guarantee controlled cracking (JPCP). The designs of such joints depending on the technical requirements are given in respective specifications. Main features for the design are aiming first for the controlled cracking at the foreseen position during young age of the concrete as well as avoidance of wild cracking during service life, second for sufficient load transfer at the joint to reduce edge load effects and third for a good long time performance, which requires joint sealing. This paper focus on research works performed in the field of joint efficiency (dowelling) of transversal joints, which is especially related to the design parameters and the positioning of dowels. New developments and alternative solutions concerning the today’s usage of coated steel bars must be done within the area of conflicts of following headings: Load transfer efficiency, longitudinal resistance, long-time behaviour (corrosion). FEM models and laboratory tests offer evaluation criteria for modified parameters. Especially the coating-material foreseen to cover the steel bar must be evaluated within the area of conflicts shown above. Additionally the actual dowel position and alignment is of importance. Non-destructive inspection tools are under development. The outputs of these investigations are strengthening the background for the updating work concerning the respective specifications.
