Method for increasing use amount of air-quenched steel slag aggregate in concrete
The invention provides a method for increasing the use amount of air-quenched steel slag aggregate in concrete, and relates to the technical field of steel slag waste recovery. Comprising the following steps: (1) weighing calcium lignosulphonate and silicon-containing powder, uniformly mixing to obtain a modifier, adding water into the modifier, and stirring and dissolving to obtain modified slurry; (2) weighing air-quenched steel slag, pouring the modified slurry into the air-quenched steel slag, uniformly stirring, standing and drying to obtain modified air-quenched steel slag; and (3) mixing the modified air-quenched steel slag with pebbles, gravels, yellow sand and cement, adding water, uniformly stirring to obtain a mixture, molding the mixture to obtain a green body, and maintaining the green body. The method not only improves the use amount of the modified air-quenched steel slag aggregate in the concrete, but also can improve the strength of the concrete.
本发明提供一种提高风淬钢渣骨料在混凝土中用量的方法，涉及钢渣废料回收技术领域。包括如下步骤：(1)称取木质素磺酸钙、含硅粉料，混合均匀得到改性剂，向改性剂中加水搅拌溶解后，得到改性浆料；(2)称取风淬钢渣，将所述改性浆料倒入所述风淬钢渣中搅拌均匀，放置干燥，得到改性风淬钢渣；(3)将所述改性风淬钢渣与石子、碎石、黄砂和水泥混合，加入水，搅拌均匀得拌合料，将所述拌合料成型后得坯体，对所述坯体进行养护。该方法不仅提高改性风淬钢渣骨料在混凝土中的用量，还能提高混凝土强度。
