    Abstract: 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.

    Abstract: A hot-dip Zn—Al alloy coated steel sheet exhibiting a beautiful coating appearance with metallic luster, in which no spangle or very fine spangles are formed, and having excellent blackening resistance and a method for manufacturing the hot-dip Zn—Al alloy coated steel sheet are provided. The hot-dip Zn—Al alloy coated steel sheet includes a hot-dip Zn—Al alloy coating layer containing 1.0 to 10 percent by mass of Al, 0.2 to 1.0 percent by mass of Mg, 0.005 to 0.1 percent by mass of Ni, and the balance being Zn and incidental impurities on at least one surface of a steel sheet. The manufacturing method includes the steps of dipping the steel sheet into a hot-dip Zn—Al alloy coating bath and pulling up and cooling the steel sheet, wherein the steel sheet pulled up from the coating bath is cooled to 250° C. at a cooling rate of 1° C. to 15° C./sec.
