Special Issue on NIED Frontier Research on Science and Technology for Disaster Risk Reduction and Resilience 2023
Authors: Takara Kaoru , Aoi Shin
Published: September 2023

We are very pleased to publish this Special Issue, NIED Frontier Research on Science and Technology for Disaster Risk Reduction and Resilience 2023, which includes three papers and one tutorial.

The first paper, authored by Dhakal and Kunugi, presents the orientation changes that earthquake movements have caused in the accelerometers of a seafloor observation network for earthquakes and tsunamis along the Japan Trench (S-net). This study is expected to contribute to more accurate analyses of S-net data. The second and third papers are reports of research done on volcanoes. The paper by Tanada and Ueda presents the seismic activity of the Nasudake volcano through the use of NIED hypocenter data gathered from 1998 to 2022. Tanada and Ueda state that earthquakes have regularly occurred near the Chausudake lava dome and two craters and that, from the volcano disaster-prevention point of view, it is important to monitor the relationship between this seismic area and volcanic activity. The third paper, by Miyagi et al., reports on an experiment aimed at grasping the movement of climbers and sharing the level of disaster threat with climber-related organizations in real time. Their online visualization system for the movement of climbers helps to provide solutions to problems related to volcanic disaster prevention not only during disaster events but also in the periods between. The last paper is a tutorial by Hanashima and Usuda on “SIP4D-ZIP,” which is a standard for synthesizing and sharing common information from multiple organizations. This tutorial explains how to realize a versatile and automatic mutual data sharing and usage system for various kinds of necessary disaster information.

In conjunction with the fourth 7-year mid/long term plan period 2016-2022, NIED has published seven special issues since 2017, including this 2023 issue. We believe that the articles in these seven issues can contribute to the advancement of science and technology for disaster risk reduction and resilience.
Analysis of Orientation Changes of S-Net Accelerometers due to Earthquake Motions
Authors: Dhakal Yadab P. , Kunugi Takashi
Published: September 2023

S-net is a large-scale seafloor observation network for earthquakes and tsunamis around the Japan Trench, consisting of 150 observatories equipped with seismometers and pressure gauges. The sensors have been set up inside cylindrical pressure vessels, which have been buried in the shallow-water regions (water depth <1,500 m), while the vessels have been laid freely on the seafloor in the deeper-water regions. Previous studies showed that the cylindrical pressure vessels rotate during strong shakings due to poor coupling with the seabed sediments, thus making it difficult to retrieve the actual ground motions. We investigated the static changes in the orientations of S-net accelerometers due to shakings from 1,878 earthquakes of Mj greater than 4 that occurred around the network, and found that rotations as large values as 16° were observed during the 2022, Mj 7.4, off-Fukushima Prefecture earthquake. We estimated the threshold acceleration levels after which the sensors are likely to rotate at all S-net stations separately and found that the threshold values lie mostly between 5 and 50 cm/s2. Finally, we discussed the observed peak accelerations and velocities at the S-net stations with those recorded on land, where high-quality records were obtained, during the 2022, Mj 7.4 earthquake, which was also the largest magnitude earthquake to occur in the region after the network commenced operation. The results presented herein complement several previous studies and form the basis for more comprehensive future investigations.
Disaster Information Sharing Technology Among Heterogeneous Information Systems Through SIP4D-ZIP Framework
Authors: Hanashima Makoto , Usuda Yuichiro
Published: September 2023

“SIP4D-ZIP,” developed by the authors, is a common data framework for sharing disaster information among systems operated by different organizations. In past large-scale disaster responses, it has often been necessary to share information that could not be predicted in advance with several organizations. Even if such information could be converted into electronic data, the valuable information was sometimes not fully utilized due to the lack of a common format for describing the meaning of the data or lack of the data format that can be read by different systems. To solve such problems, we developed SIP4D-ZIP as a common data framework that enables data to be exchanged between systems without prior arrangement. We demonstrate how SIP4D-ZIP can solve the problems found in actual disaster response, which are the background of the design concept of SIP4D. Furthermore, we explain in detail how SIP4D-ZIP works and show that it can automate the processes required to share information between systems. We believe that designing both the information source system and the utilization system based on SIP4D-ZIP will enable highly versatile and automatic mutual sharing of disaster information and promote digital transformation in disaster response.
Adolescents’ Responses to the 2017 Puebla Earthquake in Mexico City
Authors: Santos-Reyes Jaime , Gouzeva Tatiana
Published: September 2023

This paper presents the results of a cross-sectional study on adolescents’ behavioral and emotional reactions during and immediately after the 2017 Puebla earthquake that occurred in Mexico City. Convenience sampling was used to achieve a sample size of n=362. Some of the key findings are as follows: a) some 57.0% of adolescent women and over 60.0% of men “ran out of the building” during the earthquake; only 17.4% of women and 14.2% of men took shelter. Early and late adolescent women were significantly associated with building “evacuation” immediately after the earthquake. b) Early and late adolescent men were “surprised” by the earthquake occurrence. c) The perceived vulnerability of the city (PVC) was significantly associated with men but not with women. d) Adolescents exhibited strong information-seeking behavior regarding seismic risk. The results of the study highlight a lack of adolescents’ preparedness for earthquakes in terms of the protective actions taken during the ground shaking and knowledge of the functioning of the Mexican seismic alert system. An educational program aimed at better educating and preparing adolescents for a seismic emergency should be implemented in preparatory schools.
Estimation of Sales Decline Risk Based on COVID-19 as a Model
Authors: Ohori Katsumasa
Published: September 2023

Owing to the coronavirus disease 2019 (COVID-19), many companies experienced a sharp and significant decline in sales, resulting in a major crisis. This study proposes a method for estimating the risk of a sudden and significant decline in sales to tackle the aforementioned issue. The method is based on the distributional characteristics calculated from historical data of companies mainly in the transportation industry, which are vulnerable to disasters, using the damage caused by COVID-19 as a lesson. Furthermore, we conduct an empirical analysis using the proposed stochastic model for the case of the All Nippon Airways Co., Ltd. (ANA), a major Japanese airline company. The results are as follows: (1) the sales change rates are normally distributed before COVID-19, but inclusion of post-COVID-19 data produced asymmetric distribution of sales change rates; (2) the proposed statistic is log-normally distributed (including post-COVID-19 data) for a time interval of two or three years; (3) the probability of actual sales decline was estimated to be between 0.1% and 1.6% in fiscal year (FY) 2020 and FY2021 post-COVID-19; (4) the estimated risk of future sales decline is well-grounded in light of past actual values.
STUDY OF PILLAR DIMENSION VARIATIONS MODELLING ON RIVER GEOMORPHOLOGY
Authors: Muhardiono Iman
Published: September 2023

The behavior of river flow patterns on the condition of the pillar dimensions can affect the geomorphology conditions of the river, namely the unbalanced local scouring between sediment transport and sediment supply so that it will affect the strength of the pillar. This study aims to study the effect of pillar dimensions on scour depth and channel base changes in the pillar area. The method of observation was carried out by simulations using Nays2DH with the same parameters for each test of each dimension with discharge (Q) = 0.5 m3/s, sediment diameter (D50) = 0.35 mm, channel width (B) = 5 m, channel length (L) = 25 m, slope (i) = 0.005 and drainage time (t) = 7200 s. The simulation results show the basic scour pattern of the channel which has the smallest value, the diamond type pillar. Degradation - Basic channel agitation on diamond type pillars, showing a pattern that tends to be evenly distributed compared to semi rounded, rectangle, or octagonal types. Period (t) 7200 s downstream of the pillar, semi rounded type scours change <0.3 m, rectangle type scours changes <0.4 m, octagonal type scours changes <0.4 m, and diamond type scours changes <0.2 m. So the dimensions of the diamond type are more effective in reducing the depth of scour.

Authors: Hidayati Fitri , Rarasati Ayomi Dita
Published: September 2023

The Indonesian government has attempted to reduce traffic congestion on toll roads by implementing a non-cash toll transaction system that has been valid on all Indonesian toll roads since October 2017. However, heavy traffic that causes traffic congestion on toll roads in urban areas often occurs. This study aimed to find out the factors that affect the development of the toll transaction system and the extent to which vehicles will be distributed through the preferences of road users to choose to enter the toll road or not. This research method used a quantitative descriptive approach with online and offline surveys through Stated Preference. Respondents were class I – V vehicle users who crossed Prof. Dr. Ir. Soedijatmo Toll Road with the direction of travel from the Jakarta Intra Urban Toll Road. The results of the study indicated that the implementation of contactless cashless toll transactions (Electronic Toll Collection (ETC)) can reduce the interest of road users to enter toll roads if fines are imposed, but on the other hand road users are still highly interested in entering toll road because there is a toll transaction time cut service. In the congestion pricing scenario, there was an increase in the distribution of traffic volume because the number of vehicles decreased along with the reduced interest of road users to enter the toll road due to the higher toll rate increase.

Authors: Farichah Himatul , Hutama Dio Alif , Solin Dian Purnamawati
Published: September 2023

High domestic consumption of coal, especially in energy sector, has raised concerns on several environmental issues in Indonesia. Large amount of coal combustion product in the form of solid waste, such as fly ash resulting from coal power plant production causes problems in its disposal since its necessity of land occupancy. Over the last decade, many researchers have put effort to solve this disposal concerns by utilizing these materials for various purposes, such as construction materials as part of circular economy. This paper presents the utilization of fly ash for soil stabilization in Surabaya. Firstly, the index properties of soil samples were determined through a series of laboratory soil test including specific gravity, unit weight, moisture content, sieve analysis and Atterberg’s limit tests. Subsequently, standard proctor test was conducted to obtain the maximum dry density and optimum moisture content of the soil samples. Using those parameters, four types of soil stabilized with fly ash samples were prepared with fly ash content based on weight of soil as follows: 0%, 5%, 10%, and 15%. Finally, unconfined compression tests were performed with cylindrical soil samples to assess the unconfined compressive strength of those samples. The results indicate that soil with fly ash content of 10% showing the highest unconfined compressive strength compared to the other variations of 0.90 kg/cm2.

"KETIKA SANG PENYAIR BERCERITA HILAL (Nalar Ilmu Falak Muhammadiyah dalam puisi Taufik Ismail “Bulan Apa Betul, Kau Sulit Dilihat”)
Authors: Musonnif Ahmad
Published: September 2023

This research focuses on Taufik Ismail's poem entitled "Bulan Apa Betul, Kau Sulit Dilihat ". The method used is literature search and the approach used is hermeneutics to interpret the meaning of the texts contained in the poem. The poem explains Taufik Ismail's views on the debate regarding the determination of the beginning of Islamic months in Indonesia. In conveying his views, Taufik uses a dialogue model between a 13-year-old child and the moon. The results of the research through the interpretation of the text in the poem show that there is a Muhammadiyah Falak Science reasoning in Taufik Ismail's view regarding the determination of the beginning of the Islamic month in this poem. This can be seen from some of the characteristics of Muhammadiyah Falak Science, namely the belief in the regularity of the circulation of the sun and moon, where with this regularity one can predict the position of the sun and moon in the future by means of mathematical calculations with the criterion of Wujudul Hilal. Taufik is also of the view that determining the beginning of an Islamic month is a worldly affair where a person based on religion may decide in his own way.

Published: September 2023

La noción de apertura no es nueva en la educación. Sin embargo, lejos de permanecer estable, su significado ha variado mucho a lo largo de los años y de unas zonas geográficas a otras, dando lugar a un concepto complejo y con múltiples capas. El enfoque inicialmente limitado a los contenidos asociado a los Recursos Educativos Abiertos (REA) se ha ampliado gradualmente para abarcar una gama más amplia de actividades educativas, como indica el cambio hacia las Prácticas Educativas Abiertas (PEA). Más allá de la producción y (re)utilización de recursos, las PEA abarcan también aspectos como la implantación de infraestructuras educativas abiertas o la adopción de modelos pedagógicos innovadores que empoderen a los estudiantes como coproductores en su trayectoria de aprendizaje permanente.
Con este número especial, ofrecemos una perspectiva internacional (con investigaciones del Norte Global y del Sur Global) sobre la diversidad de formas y modalidades que pueden adoptar las PEA en los distintos contextos de la educación superior. Esperamos que las contribuciones de los autores sean de interés para los/as lectores/as de la Revista Edutec y que fomenten una mayor reflexión sobre laas PEA, así como nuevas investigaciones y prácticas.

Published: September 2023

A Matemática, historicamente, vem sendo significada como de difícil compreensão. Delimitando à Geometria, esta tem sido calcada na memorização de definições e fórmulas, o que nega aos alunos a possibilidade de aprendizagem do lógico histórico dos conceitos. Este artigo tem o objetivo de analisar a Atividade Orientadora de Ensino (AOE) enquanto princípio metodológico no processo de apropriação de conceitos trigonométricos. Trata-se de um recorte dos dados de uma pesquisa de mestrado em Matemática (BEZERRA, 2019), ancorada na abordagem qualitativa, que se insere em um contexto de desenvolvimento de AOE com alunos do Ensino Médio da rede pública estadual do Maranhão, Brasil. Foi subsidiada pela Teoria da Atividade e pelo próprio conceito de AOE. Como resultados, constatou-se que a AOE se apresenta como possibilidade de organização do ensino dos conceitos trigonométricos. Nessas condições, parte-se do movimento lógico histórico do conceito por possibilitar ao aluno a tomada de consciência da necessidade de encontrar uma solução ao problema desencadeador, colocando-o em atividade de aprendizagem.

Authors: Andayani Puji
Published: September 2023

This research examines the Holt winters exponential smoothing method to solve forecasting problems using case studies of the spread of Covid-19. The data source uses the transmission of Covid-19 in Indonesia. MAPE is used to measure errors in data forecasting. The results are structured to serve as a recommendation for other researchers in choosing a method for predicting the spread of the disease. Based on the results, forecasting with the Holt-Winters model in positive cases produces a MAPE value of 9.21% using the Multiplicative model and the best parameter values of alpha, beta and gamma (0.4, 0.05, 0.25). Whereas in the case of human recovery, the MAPE value was 11.86% using the Multiplicative model and the best values for the parameters alpha, beta and gamma (0.4, 0.03, 0.1). And in the case of death it produces a MAPE of 17.97% using the Multiplicative model and the parameter values alpha, beta and gamma (0.4, 0.01, 0.1). So, it can be concluded that the Holt-Winters method on human positive case data shows a good outcome performance while recovered and deceased cases produce a well-being analysis performance.

Authors: Lezani Nadine Mulya , Habibah Ummu
Published: September 2023

Burgers equation is one of the nonlinear differential equations which is generally difficult to determine its analytical solution, so it is necessary to do a numerical approach. This article discusses the numerical solution of the Burgers equation using the Cubic B-Spline Collocation method. The first step is to derive the numerical scheme using the Cubic B-Spline Collocation method for the space variable and the Crank-Nicholson method for the time variable. Furthermore, based on von Neumann stability analysis, it is obtained that the numerical scheme of Burgers equation is unconditionally stable. By performing numerical simulations using different and step sizes, it can be shown that the absolute value of the resulting error will be smaller for the step sizes of and which is getting smaller.

MEANINGFUL ACTIVITIES AND MEANING IN LIFE IN SOUTH KOREA: BASIC PSYCHOLOGICAL NEEDS SATISFACTION AS AN EXPLANATORY MECHANISM
Authors:   The Department of Humanities, Arts and Social Sciences (HASS) Singapore University of Technology and Design, Singapore, Park SaeMi
Published: September 2023

Introduction – The self-determination theory implies that autonomy, relatedness, and competence might influence the extent to which one perceives his/her life is meaningful. In addition, we examined whether the level of engagement in meaningful activities is subject to the satisfaction of basic psychological needs, which in turn is likely to form perceptions on a meaning in life. Methods – To address these questions, we analyzed survey data that is collected from South Korean adults at the individual level in March of 2023 (N=36). I conducted t-tests and a zero-order correlation before working on the serial mediation analysis. PROCESS macro model 80 is used to analyze serial meditation mechanisms including exposures to meaningful activities, basic psychological needs satisfaction, engagements in meaningful activities, and meaning in life. Results – The serial mediation model discovers two significant paths involving that higher levels of sense of autonomy have increased perceptions on a meaningful life. Also, once individuals regularly participate in meaningful activities, a sense of relatedness is shown to be enhanced. Discussion – This research can contribute to the study of public health by suggesting that beneficial psychological effects of engagement in meaningful activities have subsequent social implications through an increased sense of belongingness. More one senses autonomy, the more likely hold meaningful life perceptions. Participation in meaningful activities has to do with an increase in a sense of relatedness. Conclusion – Autonomy has a significant direct effect on meaningful life perception, which corroborates satisfaction with autonomy plays an important role in the South Korean population’s well-being. By designing initiatives is likely to enjoy greater levels of satisfaction in a sense of relatedness, implying an improved sense of belongingness to one’s network, including their neighborhood and society. Keywords: meaningful activities, autonomy, relatedness, competence, meaning in life.

Introduction – Autism spectrum disorder (ASD) is one of the neglected problems which keep increasing worldwide and contributing high burden for the parents and sufferer. Currently, there are still no definitive or effective therapy existed. Probiotics are living beneficial microorganisms which can confer health benefits as management agent in ASD children. This paper will evaluate the role of probiotics as a promising management approach to ASD based on the novel knowledge thus increasing the patient’s quality of life. Methods – A literature review evaluating the role and effectiveness of probiotics in managing children with ASD is constructed with inclusion criteria based on PICOS framework. The article search strategy is using boolean operator with the main keyword “Autism Spectrum Disorder”, “Probiotic”, “Management” to get structured and specific results. Data extracted from Pubmed, ScienceDirect, and Cochrane databases with and only papers published from 2011-2021 that are included. Results – The author reviewed 8 articles that met inclusion criteria. Studies were conducted globally in children of various ages and the probiotic intervention varies in dose and durations. All studies stating that probiotics are effective to improve the symptoms of children with ASD. The Improvement is related to autism symptoms, gastrointestinal symptoms, microbiome variety, and laboratory findings. Discuss – The improvements by probiotics are correlated to some mechanisms including control of gut integrity, restore good microbiome variety, maturation of the host immune system, signaling to CNS via ENS, correcting “opioid excess”, and oxytocin maximization. Conclusion – Probiotic has a role in managing children with ASD by improving the symptoms based on the gut-brain axis approach. In future research, it is suggested to evaluate the long-term safety and efficacy and possible combination therapy of specific bacterial species of probiotic in clical trial research. Keywords: autism spectrum disorder, probiotic, management, supplementation.

Published: September 2023

The Anxiety Disorder diagnosis is a common comorbidity of Children with Autism Spectrum Disorder (ASD). The early detection of Anxiety is essential to increase the quality of life of children, especially in kindergarten children. Thus, the study aimed to investigate the differences between parents and teachers in reports of Anxiety in autistic children 3–5 years old. We used the Screen for Child Anxiety-Related Disorders (SCARED) parent version for parents and teachers of Ecuadorian children with ASD. The statistical analyses were performed on two evaluations of the same children. The sample size was 34 parents and 34 teachers. The binomial logistic regression model for the SCARED rating to the responses of teachers was statistically significant for age (odds [OR], 0.16; 95% confidence interval [CI] 0.31-0.82) for 5-year-olds (p<0.028). The SCARED subscale for Panic Disorder, Generalized Anxiety Disorder, Separation Anxiety Disorder, and Social Anxiety Disorder is correlated with the anxiety disorder. The data are statistically significant based on teachers' responses (p <0.05). According to parents' responses, the SCARED rating did not find any relationship between the study variables and the anxiety disorder. Most children were classified with anxiety disorder when evaluated by teachers but not by parents. Identifying Anxiety in children with ASD in kindergarten can help adequately treat the disease and contribute to neurodevelopment and quality of life in childhood.

IT really matters: Associations of computer hassles and technical support with medically certified sickness absence due to mental health complaints (Preprint)
Authors: Christensen Jan , Nielsen Morten Birkeland , Knardahl Stein
Published: September 2023

BACKGROUND

Background: Information and Communication Technology (ICT) at work may cause distress and frustration among workers, known as "technostress", "computer stress", or "ICT hassles". However, few, if any, studies have examined the impact on sickness absence due to mental distress.

OBJECTIVE

The current study investigated effects of ICT hassles and potential mitigating effects of training and support.

METHODS

Methods: We surveyed 8620 workers about instances of not being able work due to problems with ICT, and about ICT-relevant support and training. Responses were linked to official registry data of medically certified absence due to psychological complaints during 12 months following the survey. We used Bayesian multilevel multinomial logistic regression to analyze relationships of ICT variables with short- or medium-term and long-term sickness absence (STSA/LTSA). Moderated regressions determined whether effects of ICT hassles varied with levels of ICT support or ICT
training.

RESULTS

Results: Reported ICT hassles predicted LTSA (OR 1.21, 95% CI 1.02,1.44) at the individual level and STSA at the work unit level (OR 1.48, 95% CI 1.13,1.93). ICT support predicted lower risk of STSA at both levels (individual: OR 0.87, 95% CI 0.76,0.99, work unit: OR 0.70, 95% CI 0.56,0.87). Insufficient or uncertain ICT training appeared to have the most marked effects, with ORs ranging from 1.49 to 1.75. All effects were strongest at the work unit level, and most persisted after adjustment for job demands and -control. No moderation of the effect of hassles by training and support was observed.

CONCLUSIONS

Conclusions: ICT hassles can have considerable negative impact on work ability, whereas adequate support and training minimizes such effects. However, offering support after hassles have occurred may not be sufficient. Support and training should, to the extent possible, be given early to prevent hassles in the first place.

Esta investigación explora la problemática de los residuos sólidos y su reciclaje en la Ciudad Colonial de Santo Domingo, República Dominicana, con el fin de conocer los factores que contribuyen a su proliferación y cómo afecta la vida de sus residentes, la actividad de los establecimientos, así como al turismo, en la percepción de quienes hacen vida en la zona. La metodología de carácter cualitativo se basó en Teoría Fundamentada, utilizando grupos focales y entrevistas semiestructuradas con residentes y dueños de negocios, además de la observación participante. Los resultados indican que la basura es un problema común que afecta tanto la calidad de vida de los residentes como al turismo. Los residentes culpan a los establecimientos comerciales, la falta de contenedores adecuados, la presencia de personas sin hogar, la irregularidad de la recolección de basura y la falta de conciencia ciudadana sobre la basura y el reciclaje. Se concluye que la educación es vista por las personas que hacen vida en la Ciudad Colonial como un instrumento clave para abordar estos problemas. Este es el primer estudio antropológico-sociológico sobre la problemática relacionada con la gestión y disposición de los residuos sólidos en la Ciudad Colonial.

Varias ciudades de Latinoamérica y el Caribe, incluida la República Dominicana, se han considerado como paraísos sexuales, espacios que también se prestan para la explotación sexual comercial infantil. La presente investigación tiene como objetivo analizar la percepción de actores clave gubernamentales y no gubernamentales acerca de la explotación sexual comercial infantil en contextos turísticos en la Republica Dominicana. El estudio se enmarca en el paradigma positivista, es de alcance descriptivo, con enfoque cuantitativo, de diseño no experimental, de campo, transversal. Se aplicó una encuesta de opinión autoadministrada, anónima, compuesta por 15 reactivos, a una muestra no probabilística de 100 agentes gubernamentales y no gubernamentales que abordan el fenómeno en diferentes provincias del país. Como resultados relevantes se destacan los siguientes: (i) contradicción entre la percepción de existencia de suficiente debate nacional sobre el fenómeno de la explotación sexual comercial infantil frente a la percepción de ineficiencia de las respuestas de instituciones gubernamentales y no gubernamentales para contrarrestar el fenómeno ; (ii) percepción de existencia de un marco jurídico nacional que garantiza de manera adecuada los derechos de niños, niñas y adolescentes, frente a la percepción de pocas denuncias y sentencias condenatorias del delito. Se concluye que la mayoría de los representantes de instituciones gubernamentales y no gubernamentales reconoce la existencia de la explotación sexual comercial infantil en contextos turísticos en la República Dominicana, así como la inefectividad de las intervenciones implementadas para su abordaje.

Published: September 2023

Abstract: This paper presents a review on the performance of aggregator of EV for power market. The EV aggregator is defined as an interface entity that aggregates the EVs to act as dispersed energy resources, enabling them to support the V2G mechanism. There are various methods to optimize the performance of electric vehical aggregator for power market. This paper analyzes the bidding strategy problem of an aggregator managing a set of electric vehicles. The electric vehicle aggregator determines the bidding decisions in the market that minimize the charging costs of electric vehicles and, at the same time, meets the driving requirements of electric vehicle users. It will take into account the uncertainty in both market prices and driving needs using a set of scenarios, which allows formulating the problem using a stochastic programming approach. The impact of the bidding decisions of the electric vehicle aggregator on market prices is also addressed in the decision-making tool. A number of illustrative examples explain how to formulate and solve this type of problems.

Published: September 2023

Abstract: SCC was first developed in Japan to achieve durable concrete structures in 1980’s. Self-compacting concrete (SCC) is an innovative concrete which can be placed and compacted under its own weight with little or no vibration effect and at the same time cohesive enough to be handled without segregation or bleeding. Adoption of SCC offers substantial benefits in enhancing construction productivity, reducing overall cost, and improving work environment. Cost reduction in the building is the primary objective in developing countries like India. This paper puts forward the applications of manufactured sand as an attempt towards sustainable development in India. It will help to find valuable solution to the declining availability of natural sand to make eco-balance. Manufactured sand is one among such materials to replace river sand, which can be used as an alternative fine aggregate in mortars and concretes. The use of manufactured sand in concrete is gaining momentum these days. The present experimental investigations have been made on concrete using manufactured sand as fine aggregate and observed the effects of crushed manufactured sand on strength properties of concrete. The application of concrete meeting the specification is of paramount importance, to ensure construction of durable R.C.C. structure. A well processed manufactured sand as full replacement to river sand is the need of the hour as a long-term solution in Indian concrete industry until other suitable alternative fine aggregate are developed.
