Abstract
Concrete made up of cement, aggregates, water & additives is the world's most consumed construction material since it is found to be more versatile, durable and reliable. Concrete is the second most consumed material after water which required large quantities of Portland cement. The production of Ordinary Portland Cement (OPC) causes havoc to the environment due to the emission of CO 2 as well mining also results in unrecoverable loss to nature. Estimated carbon emissions from cement production in 1994 were 307 MtC.Hence, it is the need of hour to find an alternative material to the existing most expensive cement-concrete. Geopolymer concrete is an innovative construction material which shall be produced by the chemical action of inorganic molecules. Fly Ash, a by-product of coal obtained from the thermal power plant and Ricehusk ash a by product obtained from milling process of rice is plenty available worldwide. Fly ash rich in silica and alumina on reacting with alkaline solution produce aluminosilicate gel that act as the binding material for the concrete. It is an excellent alternative construction material to plain cement concrete without using any amount of ordinary Portland cement. Geopolymer concrete shows a greener substitute for ordinary Portland cement concrete in some applications. This paper briefly reviews the structural properties of Ricehusk ash based Geopolymer concrete and its applications.
