Comparative Studies of Fly Ash Based Geopolymer Concrete under Ambient Condition

Arpit Soni | Chetali Shrivastava Gangwal

Abstract: Concrete is the premier construction material across the world and the most widely used in all types of Civil engineering works, including infrastructure, low and high-rise buildings, defense installations, environment protection and local/domestic developments. Concrete is a manufactured product, essentially consisting of cement, aggregates, water and admixtures. Among these, cement, i. e. binder materials and major part of concrete increase the green house effect. However, in recent years the use of concrete increased day by day due to various advantages such as good strength, long life, low maintenance etc. Due to increase in uses the environment of earth is effected. The main effect of increase is temperature that melts the glaciers and increases the water level. One of the efforts to produce more environmentally friendly concrete is to reduce the use of ordinary Portland cement (O. P. C) by replacing the cement in concrete with geo-polymers. In geo-polymer concrete cement is replaced by fly ash and alkaline solutions such as sodium hydroxide (Na OH) and sodium silicate (Na2O, SiO2) to make the binder necessary to manufacture the concrete.
