Abstract: Ordinary Portland Cement (OPC) is used for construction globally whose production is an extremely energy intensive process. Waste material has gained attention among researchers as replacement cement to fly ash in concrete making. The sense of using waste materials in concrete not only of the economic factor but the more significant aspect is to protect the environment since more solid waste are produced day by day. This causes the pollution in water bodies and loss of productive land. Geo Polymer composites are possible alternates to OPC and other blended cements. This is due to the high early strength and improved durability evidenced by resistance against acid and sulphate attack, apart from environmental effects (CO2 let into atmosphere in case of OPC). In various parts of the world, considerable researches in the field of Geo-polymer composites are conducted. Hence the experimental investigations are executed to study the effect of use of fly ash and Geo polymer as a replacement of cement. The material properties were studied, based on their properties, reference mix M25 and M30 were designed. 12 specimens tested for workability test and compressive strength. Also, we have replaced cement to fly ash with 40, 60 percentages. For each mix, workability test and strength test was conducted for 9 specimens.
