<p>PROBLEM TO BE SOLVED: To produce concrete capable of consuming, as its admixture, a large amount of incineration ash of sewage sludge ordinarily discharged in order to expand the consumptive application of the sewage sludge incineration ash and increase the consumption of the incineration ash, and maintaining workability steadily at a prescribed level. SOLUTION: This concrete is produced by mixing ground incineration ash used as an admixture into cement in a 5-50% mixing ratio of the incineration ash to the amount of the cement, wherein the ground incineration ash is produced by incinerating sewage sludge to obtain incineration ash and grinding the incineration ash, and has a <=47 deg. angle of repose and <=80μm particle size.</p> |
