A Study On Influence of Admixtures On Behavior of Concrete Mix Design

Abstract

A distinctive concrete which flows and consolidates under its own weight is distinguished as Self Compacting Concrete. In that way reduces the difficulties of insertion of concrete in problematic conditions and also decreases the time in placing huge sections and at the same time exhibits high strength and better durability features as compared to the Normal Concrete. The use of different known admixtures such as Ground granulated blast furnace slag (GGBS), fly ash, lime stone powder, Silica fumes, Rice husk ash, glass powder, volcanic ash (VA) and Cement kiln dust (CKD) etc have been proved very effective in the production of Self Compacting Concrete with satisfactory strength. Various experimental efforts have been carried out to check the effects of limited replacement of cement or aggregate on properties of Self Compacting Concrete. This paper includes review of various studies conducted on use of different admixtures / materials on strength of Self Compacting Concrete
