Recycling Of Coal Fly Ash By Ceramic Processing

(PDF) Recycling of coal fly ash by ceramic processing

Coal fly ash was used as raw material for the preparation of ceramic materials by a conventional powder technology route. Powder compacts were made from as-received fly ash, from calcined fly ash and from powder mixtures having 90% of calcined fly ash plus a low- cost mineral as additive (dolomite, CaCO3.MgCO3).
