The Romans constructed the Colosseum from a primitive form of concrete. It was made by using concrete using lime, which was burned to create quicklime, water and volcanic ash. The volcanic ash served as the aggregate and is likely the reason Roman concrete, which was 10 times weaker than the concrete used presently, but it lived even after almost 2,000 years. Moreover Pyramids were possibly made of this long lasting material the Pyramids are still in good shape, which demonstrates the excellent durability of geopolymer. This era have witnessed a lot more varieties of construction and concrete. This paper is an exploration of “Geopolymer Concrete” which offers the “greenery” construction as well as to reduce the air pollution and consumption of Cement. The Ordinary Portland Cement (OPC) is most widely used construction material, approximately for every tone of cement production 1 tone of CO2 emitted by cement factory. The Cement production is responsible for approximately 5% emission of Co2 of world. Geopolymer Concrete results from high silica rich material. A research undertaken included study of Geopolymer Concrete mix design, Workability, Compressive and Tensile strength of concrete. A low calcium fly Ash was used with both Sodium silicate solution and Sodium hydroxide solution in mix. Sodium hydroxide solution with 5M, 8 M, 10 M and 12 M concentration, Sodium silicate to sodium hydroxide ratio is 2.0 was used .The ratio of Alkaline liquid to fly ash 0.49, heat curing was adopted at 60 + 5°C for 24 h and room temperature curing at 23 + 2°C.
