Fly ash is the most mineral residue left over from burning coal by coal-fired power plants. Fly ash bụ pozzolanic, meaning that it has cementitious properties. It is valuable for use in ready-mix concrete as a partial replacement for Portland cement. Ọzọkwa, it may be used in the manufacture of other building materials such as bricks, taịl, and blocks.
