Concrete being one of the most versatile, reliable and durable construction materials is the second most consumed entity in this world. Cement is the major constituent used in the manufacture of concrete whose production results in huge emission of carbon dioxide. The use of industrial wastes like fly ash, silica fume, GGBS etc cause disposal related problems and their reuse is emphasized. In this project the materials used for GPC are fly ash, fine aggregate, coarse aggregate and catalytic liquid system and an attempt has been made to determine the compressive strength of M20 grade geo polymer concrete with different molarities like 10M,12M,14M. The compressive strength of concrete at the age of 7,14 and 28 days is determined after 24 hours of oven curing at 60ºC on cubes of size 150mmX150mmX150mm. The solution (Mixture of NaOH&Na2SO3) to fly ash ratio is 0.35.The solution mix ratio i.e. NaOH to Na2SiO3 is taken as 2.5.
