Durability of Fly Ash Geopolymer Hybrid Concrete in Seawater, Sulfuric Acid, and Fire Resistant – A Review

Fly ash is a hazardous and toxic waste material from burning coal. However, it can be used as a material of geopolymer concrete because it contains high amounts of silica and alumina. Recent research on geopolymer concrete is still being conducted because it is part of green building material. This review aims to determine and analyzed the durability of fly ash geopolymer hybrid concrete in aggressive environments. The environment studied...
