    摘要: A hardened product of coal ash having strength sufficient as a civil engineering or construction material is obtained by treating coal ash with sulfuric acid and/or hydrochloric acid to obtain a first reaction mixture; treating the first reaction mixture with calcium carbonate to obtain a second reaction mixture; mixing the second reaction mixture with a hydraulic material and water to obtain a third reaction mixture; and shaping and curing the third reaction mixture.
