Concrete is used more than any other man-made material in the world, in fact it is the second most consumed substance in the world after water. The production of concrete is the reason for the emission of 5% of total global emission. This is high time to think for an alternative to cement since the production of cement is the main reason for emission. There are considerable attempts which have taken place in order to replace cement with other materials. One of those is Geo-Polymer Concrete (GPC). [1] This study investigates the feasibility of using a blend of 50% ground granulated blast furnace slag (GGBS) and 50% fly ash as precursor material for geopolymer concrete production. Also fine aggregate has become very expensive and scarcity, quarry rock dust have been replaced for fine aggregate. Almost all the demolition and construction waste have been dumped without any usage which ultimately results in pollution. [2] This prime factor is considered to reutilize recycled coarse aggregate instead of coarse aggregate. A greener aided with natural friendly claim can be made only with the usage of the waste materials. To find the better combination mix, the GPC is categorized into four types as GPC-1, GPC-2, GPC-3 and GPC-4.all the above combinations of mixes fly ash is used as prime source material whereas QRD and RCA are in replaced with different combinations. Thus, this paper particularly focuses on the effect of replacement of waste materials in combination of different mixes such as FA+CA, QRD+CA, FA+RCA, and QRD+RCA in GPC. The cast specimens are cured at ambient temperature and after three days of rest period, the cast specimens are tested to determine its mechanical strength properties using standard methodology.
