Experimental Investigation on Polymer Modified Ternary Blended Concrete

Abstract

Research in the field of concrete has led to the development of various new types of concrete which are superior to conventional concrete with respect to strength and durability. One such type of concrete is the polymer modified concrete, in which polymer is added to the concrete during the mixing stage of the ingredients of concrete to modify its properties in fresh as well as in its hardened state. The main objective of this experimental study is to investigate the behaviour of polymer modified ternary blended concrete with varying percentages of polymer in it. Different percentages of silica fume are replaced and polymer addition are studied as 8%, 12% and 0%, 1%, 2%, 3%, 4%, 5%, & 6% respectively. Quantity of fly ash replaced is 30%. The investigation carried out in this work shows that the addition of polymer modified ternary blended concrete with 8% silica fume (cement replacement), 30% fly ash (cement replacement) and 3% styrene-butadiene rubber latex polymer is stronger than polymer modified ternary blended (PMTB) concrete made with 12% silica fume (cement replacement), 30% fly ash (cement replacement) and 2% styrene-butadiene rubber latex polymer.
