Fly-Ash consists of inorganic, incombustible matter present in the coal that has been fused during combustion into a glassy, amorphous structure. Fly-Ash is a pozzolanic material i.e. it is a siliceous or aluminous material that when mixed with lime and water forms a cementations compound. That capability is one making fly ash a desirable admixture of concrete.
