Characterisitics Examination of Bentonite Mortar with Replacement of Cement

Abstract

The experimental investigation on alternate concrete from aged volcanic ash or hydrated aluminium silicate was done by partially replacing bentonite with OPC. Bentonites consist of the fundamental elements of cement like silica, magnesium and calcium. The total assets of bentonite in the country are about 531 million tons bulk of the resource in Tamil Nadu.The partial replacement of bentonite with cement leads to reduction of cement content in concrete mix and furthermore decreases the transfer and contamination issues. Cylinders and cubes were casted and tested for the 7th, 14th and 28th days respectively.10, 20, 30, 40 and 50% replacement of bentonite with cement are done. Slump test are also done to study the workability characteristics of replacement concrete according to Indian standards. Finally the estimation was computed for all the partial replacement of concrete samples of bentonite according to percentage of mix.
