Abstract:

Recent years have seen widespread growth in Portland cement concrete. Infrastructure growth has increased concrete demand. Durability and carbon dioxide emissions are issues with Portland cement concrete. Carbon dioxide pollution from Portland cement production and waste growth can be reduced in many ways. Indian thermal power stations produce 120 million tonnes of fly ash annually. Land disposal deficiencies make it a major issue. A modern pozzolanic material rich in Silicon and Aluminium like fly ash called " Geopolymer concrete " replaces cement. Industrial solid wastes and byproducts were recycled to make geopolymer concrete. Fly Ash, a thermal power plant byproduct, is abundant worldwide. Fly ash improves concrete properties and is suitable for consumption. To introduce geopolymer technology and the many materials that can be synthesised by alkali activation of alumino silicates, this paper provides a brief history and review.
