Fly ash is an industrial by-product from coal-burning for generating electricity. Class F Fly ash is obtained as a fine powder primarily consisting of alumino-silicate glass. It is blended into cement and concrete to create improved workability and long-term strengths, to reduce permeability, and to increase resistance to sulphate and chloride attack. ENVIROCore 201 is a supplementary cementitious material available in bulk.
