Geo-polymer Concrete is mainly hardened cementitious paste made from fly-ash and alkali solution. It helps to combines waste product into useful product. In this the major point is to investigate the solidity parameters of GPC utilize varying proportions of fly-ash, GGBS & Silica fume in addition to alkali solution (Na-OH and Na2SiO3), which reduces demand of OPC which leads to the emission of CO2 to the environment and to produce a more durable infrastructure. With various advantages of these materials as studied in detail in this project, better strength parameters for Geo-polymer concrete are expected by using varying proportions of Fly-ash, GGBS, Silica-fume along with an alkali solution (NaOH and Na2SiO3) than conventional concrete. Thus, Geo-polymer concrete helps in the complete replacement of Portland cement and act as an environmentally friendly material by the reduction of CO2 emission to the society which leads to control the environmental pollution. It is expected that centralizing over needs & examining in a way that includes a lot of careful detail in this area will help to materialize flue-ash based GPC as a trading & non-polluting material also set the seal on the sustainability of construction. © 2021 Elsevier B.V., All rights reserved.
