Abstract:

Concrete prepared with Ordinary Portland Cement (OPC) is well known in the world for its reliability durability and versatility. OPC concrete is the second most used material next to water. Even though OPC is so popular in construction, it is not eco friendly due to enormous energy consumption in its production and due to emission of enormous CO2. This is posing a serious challenge in sustainable development. Efforts are needed to develop a environmental friendly civil engineering construction material for minimizing emission of green-house gases to the atmosphere. The Endeavour to develop a environment friendly concrete had offered many alternatives. One eminent among them is geopolymer concrete. This paper presents a review summary of detailed literature survey conducted on geopolymer concrete. In geopolymer concrete, the inorganic alumino-silicate polymer gel synthesized from source materials rich in silicon and aluminium, such as low calcium (class F) fly ash, Ultra-Fine GGBS, High calcium Fly ash, M-Sand and Fly Ash , Recycled Aggregates and Metakaolin and GGBS which binds the loose aggregates, and other un-reacted materials in the produced geo-polymer mix. Geopolymer cement, because of it environment friendly nature becomes a most suitable alternative to OPC. This is because, with the usage of geopolymer cement, Portland cement can be dispensed with in making concrete. This paper briefly reviews the durability studies such as resistance to acid, high temperature, resistance to sulphate and chloride of geopolymer concrete.
