An Investigation on the Characteristic Properties of Concrete Containing Bentonite

Abstract

Pozzolanic reaction in concrete is gaining importance these days because of the extra development of the strength in the later ages of concrete. Some of the important pozzolanas that are commonly used in concrete are flyash, silica fume, blast furnace slag, micro silica 600 etc. the addition of these pozzolanas to concrete not only increase the strength characteristics of concrete but also other properties of concrete too. Bentonite is another pozzolana that can be used in concrete. On an average the silica content of Bentonite varies from 50% to 60%. In this an attempt is made to study the various properties of concrete containing Bentonite in different percentages. The properties of concrete like compressive strength, tensile strength, flexural strength, impact strength, and workability properties etc. are found for different percentage addition of Bentonite like 0%, 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%.
