Experimental Programme on FRC with OPC only and FRC with OPC and Mineral Admixtures

Abstract

Due to urbanization and population growth, the Construction industry is increasing rapidly over a few decades at the same time leads to increase in global warming too. In the construction, the main ingredient, Concrete which contains large amount as cement which act as a binder and Natural sand(River sand) as fine aggregate .During the cement production large co2 emits, which is mainly responsible for global warming as well as natural sand leads to Environmental degradation. So, in order to minimize this phenomenon's as well as to enhance advancements in construction industry an attempt is made in this research work to replace the cement partially with supplementary materials known as mineral admixtures. The mineral admixtures such as Fly ash, Ground granulated blast furnace slag (GGBS) and Metakaolin which are by products of industries which usage in concrete as cement replacer decrease the co2 emissions as well as disposal problems of industries and replacing natural sand with M-sand Strength as well as durability properties of FRC (@1% steel fiber by weight of binder) made with 100% OPC with different water binder ratios and concrete grades M25 and M40 were found. And then FRC made with OPC and mineral admixtures up to 45% with fly ash, Metakaolin and GGBS in different combinations were tested for strength and subjected to durability tests. For comparison durability and strengths were performed on M40 grade mix without fibres. It is observed during the analysis of tests FRC with mineral admixtures has performed better than that of FRC made with 100% OPC.
