Environmental issues resulted from cement production have become a major concern today. To develop a sustainable future it is encourage to limit the use of this construction material that can affect the environment. Geopolymer is the best solution reduce the use of cement in concrete. Geopolymer is the hardened cementious paste made from fly ash, alkaline solution and geological source material.Fly ash is finely divided powder produced by coal and fired power station .RHA is the bye-product of paddy industry. RHA is rich in silicaabout 90%, 5% carbon and 2% K2O. The specific surface area of RHA is about 40-100 m2/g. As per study it is found that incorporation of RHA upto 30% replacement level reduces the chloride penetration, decreases permeability and strength and corrosion resistance properties.
