Experimental Investigation in Effect of Low-Calcium FlyashGeopolymer Concrete

Geopolymer concrete results from the reaction of a source material that is richin silica and alumina with alkaline liquid. A summary of the extensive studies conducted on fly ash-based geopolymer concrete is presented. Geopolymerconcrete utilizes an alternate material including fly ash as binding material inplace of cement. This fly ash reacts with alkaline solution (e.g. NaOH) andSodium Silicatec(Na2SiO3) to form a gel which binds the fine and coarse aggregates. One kinds of system were considered in this study using 100% replacement of cement by ASTM class F flyash. It was analyzed from the testresult that the Indian standard mix itself can be used for the geopolymerconcrete with some modification.
