Ghosh, Rachit and Kumar, Anil and Kumar, Sanjay (2013) Flyash Geopolymer Concrete as Future Concrete. International Journal of Advanced Scientific and Technical Research, 6(3) . pp. 260-271.
Demand for concrete as construction material is on the increase so as the production of cement. It is estimated that ~6-8% of total CO2 is generated from construction industry. To reduce the concrete industry‟s carbon footprint, blended cements are in use in the market. The research trend is directed towards more eco-friendly concrete such as geopolymer. Recently the focus of research has been shifted on use of fly ash for geopolymerisation. This is based on the alumino-silicate composition of fly ash, it‟s easy availability, better flow ability and improved durability. The chemical composition of geopolymer is similar to that of zeolite, but amorphous in microstructure. Flyash-based geopolymer concrete show excellent short and long-term properties. The properties and uses of geopolymers are being explored in many scientiﬁc and industrial disciplines like modern inorganic chemistry, physical chemistry, colloid chemistry, mineralogy, geology, and in all types of engineering process technologies. The current paper presents scope of flyash based geopolymer concrete as future concrete, summarizes and critically analyses the most important research ﬁndings.
