Optimizing Concrete Mixtures with Red Soil as a Partial Fine Aggregate Replacement: an In-depth Investigation

Abstract

An experimental investigation is carried out to study the behavior of concrete by replacing the fine aggregate with locally available red soil. It involves a certain test to find the quality improvement of concrete when red soil is added to it. The partial replacement of sand with red soil has been done according to the specific mix proportion to gain good strength in concrete. In past studies of the journal main problem arising that increase of red soil is to reduce the strength of concrete and it absorb more amount of water. In this project, it is preferred to analysis the strength of M20 Concrete and the amount of red soil is to be added in following percentage such as 15%, 30% & 45%. Mechanical properties such as compressive strength, split tensile strength, flexural strength tests have been carried out for red soil mixed concrete and plain concrete to differentiate the strength and imperviousness in it. The tests are done during 7th, 14th & 28th days after curing.
