Recent Advancements in Geopolymer Concrete using Class-F and Class-C Fly Ash

Abstract

In recent decades, to depreciate usage of ordinary Portland cement(OPC) for the construction industry, enormous research work is going on high rich Al-Si waste materials as source material for producing Geopolymer concrete(GPC). In this paper, a review is done in three ways namely A) To study the short term and long term characteristics of various types of fly ash based Geopolymer concrete(GPC) and B) Development of Hybrid Geopolymer concrete, by partial replacement of fly ash with high calcium materials like Cement, slag and . C) Field applications of Geopolymer concrete (GPC); The research papers published are thoroughly reviewed to identify the research gap .
