Abstract: Cement is used for construction purposes nowadays but it also leaves a large amount of carbon footprint behind which is not good for our environment so we need something else which is good for both construction and environment. Here comes geopolymer concrete this concrete is produced with the help of industrial waste such as fly ash, metakaolin, GGBS (ground granulated blast furnace slag). So by using geopolymer concrete we can protect our environment from the carbon impact of cement production. In this study, 7 days and 28 days compressive strength, split tensile strength, flexural tensile strength of samples were found out. As we know that geopolymer concrete is a new type of concrete that does not require the presence of OPC (ordinary Portland cement) as a binding material instead it use fly ash and GGBS that are rich in silica and alumina.
