In India, the increased demand for construction industry required to meet the needs for infrastructure development. However, the production of Portland cement, releases the significant amounts of CO2to the atmosphere. Therefore, it is necessary to look for sustainable solutions for future concrete construction as next generation construction materials, by the use of the Secondary Cement Replacement Material (SCRM). The alternative replacement for Ordinary Portland Cement (OPC) can be Ground Granulated Blast Furnace Slag (GGBS), Fly-ash, Silica fume, Rice-husk ash, which are the various industrial by-products.In this present work, an attempt was made to develop Alkali Activated Slag Concrete (AASC) using Precious Slag (PS) ball as fine aggregate. The development of AASC was made with GGBS as the principal binder. Mixes were developed with binder content 443 kg/m, Na2SiO3/ NaOH ratio (1,1.5,2 and 2.5) and their performance when exposed to ambient temperature were studied. Alkali binder ratio (0.3) and Molarity of 8M was kept constant for all the AASC mixes. The test results showed that the slump values for the different mixes developed herein to be greater than 25mm with conventional slump cone satisfying the MoRTH guidelines for concrete pavements. Results showed that all AASC mixes have higher 28day compressive strength of the order 2458 MPa. The fatigue life of AASC mixes has improved by the addition of PS ball, at the higher concentration of sodium silicate, indicating better performance of AASC mixes.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":"158 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80035005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another purpose of this study is to know the probability of cracking based on the existing cracking assessment based on Korean methods as Indian specifications are non-existent and also to find the crack index for internally restraint cases based on temperature difference, both the elastic; hypoelastic models. The study indicated that the existing provisions based on crack index appear to be very conservative which tend to overestimate the probability of crack occurrence compared with construction observations on prototype structures.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89577148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even slight variations in ingredients can have adverse effect on fresh properties; strength and durability of hardened concrete. The material science approach to study rheological properties is essential in order to overcome the paucity posed while characterizing mixes by empirical methods such as the slump flow test. In the present the Bingham parameters of SCC were assessed by using the new concrete shear box. The mixes were designed considering volume of paste based on absolute volume concept. Three different volumes of pastes (0.38, 0.40 and 0.42) with water contents of 170 and 190 lt/m 3 and cement contents of 300 and 450 kg/m 3 along with slag as filler was used. A unique test procedure was followed, by applying low normal stresses of 0.10, 0.20 and 0.30 MPa with three different displacement rates of 1, 5 and 15mm/min under static condition. The results indicate that the new concrete shear box shall effectively put to use, as an additional tool for evaluating the rheological properties of SCC viz., yield stress and plastic viscosity.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76707388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
