Provides unique self-hardening characteristics. Reduces permeability. Provides high early strength. Useful in soil stabilization. Reduces bleeding and segregation in plastic concrete. Reduces drying shrinkage. Lowers heat of hydration.Classification of Fly ash Type of Fly Ash as per IS Codes (IS 3812-1981) Grade I: – It is derived from bituminous coal having fractions (SiO2 + Al2O3 + Fe2O3) greater than 70 %. Grade II: – It is derived from lignite coal having fractions (SiO2 + Al2O3 + Fe2O3) greater than 50 %. Type of Fly Ash as per American Society for Testing and Materials (ASTM C618)Disadvantages of fly ash: A few hours after pouring it changes from liquid to solid but the curing process may take longer. It can prolong the time as concrete takes more time to set. It reduces the amount of air ingress,
