Effect of Curing Condition on Bentonite Concrete

Abstract

The main aim of this study is to find substitute of cement because production of cement produces a huge environmental impact and study the effect of curing condition on the bentonite concrete and ordinary concrete. In this study, bentonite was replaced with percentages of cement (5, 10, 15 and 20%) in comparison with the control mix. The properties such as compressive strength, split tensile strength and chloride migration were studied under normal conditions and under steam curing. The compressive strength and tensile strength were observed for all mixes after 28 days cured in water and cured in steam, and a comparison is made between them. The ability of chloride ions to penetrate into concrete was evaluated through chloride migration test. The results showed that compressive strength and split tensile strength of concrete mix BN-5 with steam curing was the greatest among various mixes. The chloride migration was lowest for BN-20 with steam curing among the various concrete mixes.
