Authors: Bodnar Yurii , Bosetskyi Maksym
Published: August 2024

The influence of "cold bridges" on the reduced heat transfer resistance of wall enclosures, which characterizes their thermal insulation properties and energy efficiency, was studied. A nine-story monolithic frame residential building in the city of Lviv was considered. Wall enclosing structures 250 mm thick made of hollow ceramic blocks on a cement-sand mortar. The thermal insulation of the walls is made by the wet method with plates made of mineral wool 100 mm thick. Windows and transparent facade systems made of PVC profiles filled with double-glazed windows. The following heat-conducting inclusions were considered: mineral wool fastening dowels, window slopes, inter-floor and balcony ceilings, columns, corner joints. To determine the reduced heat transfer resistance, modeling of wall nodes was performed using the finite element method using the Agros2D software complex. As a result of the calculations, the temperature fields and heat flows for the corresponding nodes with "cold bridges" were obtained. Based on calculations of two-dimensional temperature fields of wall fragments, linear heat transfer coefficients for linear heat-conducting inclusions were calculated. The reduced heat transfer resistance for the external walls of the building in question was determined, taking into account the named "cold bridges". The results indicate a significant influence of these heat-conducting inclusions. The influence of each heat-conducting inclusion on the heat transfer coefficient was evaluated. It is concluded that heat transfer inclusions such as ceilings have the greatest impact on heat transfer for the house under study. The results of the research will be useful in the analysis of energy efficiency and the design of multi-story residential buildings with a monolithic frame.

Published: August 2024

According to the results of the research analysis, the existing hydrostatic levels used in construction for high-precision assembly of elements of buildings and structures, engineering networks and technological equipment have been characterized. Their design features, advantages and disadvantages, accuracy of measurement of excesses are determined. The design of a hydrostatic leveler is proposed for determining significant amounts of excesses exceeding the height of interconnected vessels. The device contains basic and non-basic vessels filled with working fluid and hydraulically connected to each other by a flexible pipeline. A spring-loaded float is placed in the non-basic vessel, rigidly connected to the rod, which can freely move vertically. Vessels are equipped with heel pads to install them at the points between which the excess is determined. Scales for taking readings are applied to the dishes connected to each other. The formula for determining significant excesses is given, taking into account the correction for the amount of compensation of excess pressure of the working fluid, taking into account the force perceived by the damping devices. A refined formula is proposed for determining the mean square error of determining the excess by hydrostatic leveling, taking into account the error due to the inaccuracy of compensation of the excess pressure of the working fluid, taking into account the pressure damping force.

Published: August 2024

Paper, like the invention of the wheel, is one of the greatest achievements of mankind. At the same time, the volumes of paper production are constantly increasing, while wood reserves decrease. Accordingly, the nature is significantly damaged, and if a mankind does not stop in its insatiable desire to reduce green spaces, Earth atmosphere will soon become unsuitable for the existence of almost all types of life. Therefore, it is necessary to save forest resources in order to provide the ecological balance on the planet. In addition to wood, a lot of water and electricity are needed for paper production using traditional "wood" technologies. For instance, until recently, up to 1000 tons of water was used in the technological process to produce 1 ton of paper. Besides, after the manufacturing process, the contaminated wastewater is discharged in water bodies and other environments. Fire and high flammability of paper are also a significant danger. At the same time, 20% of the world's wood harvest is used for paper production, which causes reasonable opposition from environmentalists. Therefore, taking into account the decarbonization of Ukraine’s and the world’s economy, it is important to refuse traditional wood technologies and look for alternative wood-saving methods and methods of paper products production and relevant construction materials manufacture using a paper.

Published: August 2024

An overview of modern research and experience in the use of fly ash in construction is carried out, examples of successfulcases of its application are given.The prospects of using fly ash, which occurs during the burning of coal in thermal power plants, in construction were studied.Fly ash, which is a byproduct of coal combustion, has great potential for reuse in the construction industry, which contributes toreducing the environmental burden and increasing the efficiency of the production of construction materials.The paper discusses in detail different methods of fly ash activation, such as mechanical, chemical and thermal activation, aswell as combined approaches that combine these methods to achieve optimal results. Mechanical activation involves increasingthe specific surface area of ash by grinding it, which helps to increase its reactivity. Chemical activation involves the use of various chemical reagents to increase the activity of ash, and thermal activation is based on increasing the solubility of silica and alumina with increasing temperature.Particular attention is paid to the use of nanomaterials, such as nanosilica, nanotitanium and nanoalumina, which cansignificantly improve the properties of construction mixtures. Nanomaterials help increase strength, reduce porosity and improve water resistance of mixtures. The use of polymer additives, such as polyvinyl acetate, latexes and polyethylene glycol, which increase the adhesion, elasticity and water resistance of building materials, is also considered.The influence of ash on the strength of building materials, as well as their resistance to aggressive factors, is considered. Inaddition, the impact of using ash on the energy efficiency of building materials and reducing carbon dioxide emissions isconsidered.The development of new formulations of construction mixtures using fly ash helps to increase their strength, durability andenvironmental safety. The article gives examples of the practical application of such mixtures, in particular, in self-leveling screeds for floors, plaster and putty mixtures, adhesive mixtures for tiles and waterproofing materials. Key benefits of these innovative solutions are highlighted, including lower production costs, improved material performance and reduced environmental impact.The research results show that the use of fly ash in construction has great potential. It allows to reduce the use of primarymaterials, improve the quality of construction materials and reduce the negative impact of the construction industry on theenvironment.The article emphasizes the importance of using fly ash and innovative additives for the sustainable development of theconstruction industry and suggests promising directions for further research in this field.
HYDROPHOBIZATION OF CONSTRUCTION PRODUCTS USING EQUIPMENT FOR CYCLIC HYDROTHERMAL SATURATION
Authors: Horyun Oleh
Published: August 2024

Hydrophobization of construction materials is a relevant area in the context of processing construction materials to improve their properties. Moisture protection significantly enhances the performance characteristics of materials, increases their durability, and reduces maintenance and repair costs. Modern technologies, equipment, and materials open up new opportunities for effective hydrophobization, making this area of construction material improvement an integral part of modern construction.
The article discusses current approaches to hydrophobization of construction products, including methods of surface and volumetric hydrophobization. The main principles and technological aspects of the hydrophobization process, which include the use of hydrophobizing agents and methods of their impregnation, are described. Theoretical foundations and analysis results of literary sources dedicated to this topic are presented. The advantages and disadvantages of applying different technologies in construction practice are highlighted. It is established that modern hydrophobization technologies do not always ensure the necessary level of efficiency in the hydrophobic treatment of construction products, thus requiring improvement. In view of this, the most promising direction is identified as volumetric hydrophobization of construction materials, which involves the impregnation of hydrophobic compositions into the capillary-porous structures of samples using vacuum and excess pressure.
Equipment for cyclic hydrothermal saturation and its use for hydrophobization of construction products is proposed. Special attention is given to the analysis of the effectiveness of this method compared to traditional hydrophobization methods in the context of improving water resistance and frost resistance of construction materials. A description of the equipment's operation, which involves impregnating construction products through pulsed changes in the pressure of the hydrophobizer with specified temperature, pressure magnitude, and pulse repetition frequency, is provided.
THE SHEAR CAPACITY OF THE REINFORCED CONCRETE BRIDGE BEAMS

Published: August 2024

The article considers the solution of the scientific and practical problem of specifying the shear capacity of reinforced concrete bridge beams. Solution of the problem is based on example of the reconstruction of the bridge across the river Southern Buh in Chernovol street in Vinnytsia. These beams with a span of 7.5 m rest on the upper structures of the main spans of the bridge with a length of 45 m. Calculations according to current standards showed that the shear capacity of the beams is insufficient and they need to be strengthened. Additional research by the field test method made it possible to specify the actual level of stresses in the cross-sections of bridge beams and the actual nature of cracking along length of beams. Based on these data, repeated calculations were made to check the shear capacity of the bridge beams. These calculations made it possible to identify additional reserves of the bearing capacity of the inclined cross-sections of the beams and to abandon the need for strengthening. The identified reserves of the shear capacity are partially due to a cautious approach when determining and taking into account the initial data for the calculations of structures that have been operated for a long time without proper technical support. In addition, modern standards for the design of reinforced concrete structures in terms of ensuring the shear capacity do not allow taking into account the peculiarities of the operation of reinforced structures, are based on simplified models of the operation of reinforced concrete beams at the supporting sections and therefore require further development and improvement.
PROSPECTS OF USE OF SECONDARY WASTE OF THE CONSTRUCTION INDUSTRY IN THE PRODUCTION OF DRY BUILDING MIXTURES
Authors: Bondar Alona , Khristych Oleksandr , Bondar Oleksandr , Safronenko Ivan
Published: August 2024

The work considers the actual problem of creating effective dry construction mixes (DBC) for a wide range of construction works, in particular for external and internal plaster coatings. The main attention is paid to the study of the effect of finely dispersed mineral additives, such as diatomite, white carbon black (amorphous microsilica) and limestone powder, on the physical and mechanical properties of SBS. In the study, two working compositions of SBS based on cement binder with different types of sand were used: quartz, polymict, and screening of crushed limestone.
The results of experimental studies showed that the introduction of Tylose cellulose esters significantly increases the water-holding capacity of mortar mixtures to 99.4-99.7%. However, despite the increase in water holding capacity, these mixtures do not reach the required strength for the grade above M100 without increasing the amount of binding material. At the same time, the introduction of C-3 superplasticizer effectively reduces the water-cement ratio (W/C), which helps to increase the strength of the hardened solution and allows to achieve the required strength indicators even for the M150 grade.
Active mineral additives, such as finely ground limestone, stabilize the cement paste and help reduce delamination of the mixture. Additive grains fill the spaces between cement grains, increasing the packing density of solid components and, thus, improving the structuring of artificial stone. This helps to increase the strength and reduce the shrinkage of solutions.
It is also important that the use of local raw materials, such as waste from stone mining and sandstone processing, allows to significantly reduce the cost of production of dry building mixes. The use of these materials provides not only economic benefits, but also helps reduce the environmental burden due to waste disposal.
The results of the study confirm the perspective of using carbonate finely dispersed mineral additives as part of dry construction mixtures, which allows to improve their physical, mechanical and technological properties. This opens up new opportunities for creating effective building materials that meet modern requirements of quality and economic efficiency.

Authors: Morgun Alla , Zhengfen Tian
Published: August 2024

The article discusses the method for predicting the bearing capacity of bored injection piles constructed using the "Soletanche" technology, employing the Boundary Element Method (BEM). Considering that bored injection piles compact the soil during their installation, the study of the stress-strain state (SSS) of such structures is highly relevant.
The authors conducted mathematical modeling of the deformation process of a bored injection pile in loess clay, using solutions from an elastoplastic soil mechanics problem. The modeling was performed using an integral equation, which allows reducing the dimensionality of the problem. The main tool for calculations was the Mindlin solutions, which best corresponded to the physical nature of the problem.
The article also utilized a non-associated plastic flow rule to describe plastic deformations and the Mises-Schleicher-Botkin yield criterion. The authors presented a detailed step-by-step loading and problem-solving algorithm, considering the weighted average physical and geological characteristics of the soil.
The modeling results were compared with experimental data, confirming the validity of the proposed mathematical model. According to the obtained data, at a settlement of 2 cm, the bearing capacity of the pile using BEM was 472 kN, which closely correlates with the experimental results.
This research is of significant importance for the design of pile foundations, especially in conditions where complex geotechnical factors and nonlinear soil properties need to be considered.

Background: Brain metastases are serious complication of breast cancer (BC) that poses a critical management challenge. Hence, this study aimed to evaluate clinical findings, the status of hormonal receptors, and their correlation with brain metastasis among patients with BC. Materials and Methods: This cross-sectional study was performed on women with BC that was newly diagnosed with brain metastasis from 2020 to 2023. Also, hormonal receptor status (such as p53, estrogen receptor [ER], progesterone receptor [PR], human epidermal growth factor2 [HER2]), histopathological type of BC, duration of disease, type of treatment, local cerebral invasions, and initial presentations were recorded. A P-value less than 0.05 was considered as statistical significance. Results: Of a total of 302 patients, 49 (16.2%) patients had brain metastasis. The mean age of patients was 45.21±8.3 years, which was significantly lower in patients with metastasis (45.96±11.31 vs. 51.13±12.61 years, P=0.008). There was a significant association between the duration of disease in patients with and without brain metastasis (2.76±1.03 vs. 5.55±3.32 years, P=0.002). Also, the most prevalent histopathological type of BC was invasive ductal carcinoma (IDC). Headache was the most common clinical presentation among patients with brain metastasis. In addition, the most and the least common positive receptors among patients with metastasis were Ki-67 (93.87%) and PR (55.1%), respectively. Compared to patients without metastasis, HER2-positive and P53-positive receptors were markedly associated with brain metastasis (P=0.03 and P=0.021, respectively). However, there was no significant association between treatment methods and metastasis status.Conclusion: Patients with younger age, IDC, and positivity of HER2 and P53 receptors were at an increased risk of developing brain metastases.

Published: August 2024

AnIn Vitro study conducted at the NM-AIST Laboratory in Arusha, Tanzania,investigated the efficacy of Biochar in managing aflatoxin contamination in groundnuts, both independently and in combination with Aflasafe. Various concentrations (2 X 102, 2 X 104, 2 X 106, and 2 X 108) of atoxigenic biocontrol strainsextracted from AflasafeTZ01were introduced to the groundnut grainstreated with 5%, 10%, 15%, and 20% maize cob Biochar. All groundnuts were inoculated with atoxigenic A. flavus(2 x 106) and incubated at 30°C for seven daysbefore aflatoxin quantification using HPLC. The Analysis of Variance (ANOVA) conducted on the data revealed a significant(P < 0.001) difference among the means in reducing aflatoxins B1, B2, G1, and G2. Notably, there existed an inverse relationship between the concentration of Biochar and aflatoxin content, with the most substantial reduction observed at a 10% Biochar rate. Moreover, integrating Biochar with the Aflasafe biocontrol option further decreased aflatoxin contamination. For example, applying10% Biochar along with 2 x 106Aflasafe resulted in an impressive 99.99% reduction compared to the control. In comparison, using Biochar or Aflasafe alone led to reductions of 80.6% and 90%, respectively.These findings hold significant implications for the agricultural sector, suggesting that the strategic utilization of Biochar and Aflasafe can substantially mitigate aflatoxin contamination in groundnuts. This offers a promising solution to a significant food safety issue, providing hope for a safer and healthier food supply.
