Effect Of Differnet Curing Techniques For Fly Ash And Slag Based Geopolymer Concrete

Abstract

Cement production being highly energy intensive and emits lot of gases in atmosphere and hence it is not sustainable in future. Efforts to replace this technology with green material is need of hour. One of them is use of industrial waste by product like fly ash and slag into useful products by alkaline activation known as geopolymer concrete. In the present study different curing techniques like oven curing, ambient curing, different percentage of saline water curing and high temperature curing is done to find its effect on geopolymer concrete produced by combination of fly ash and slag as source material. Since it is found that fly ash based geopolymer concrete requires some external heat to initialize and give high early strength, an attempt was made to observe the effect when combination of material is done.
