Cementing material prepared from casting waste ash
The invention relates to the technical field of building materials, in particular to a cementing material prepared from casting waste ash. The invention discloses a cementing material prepared from casting waste ash. The cementing material is prepared from 80-85 parts of a casting fly ash mixture, 15-20 parts of a casting regenerated ash mixture, an exciting agent accounting for 1-4% of the total mass of the casting fly ash mixture and the casting regenerated ash mixture, and inorganic aluminate accounting for 5-10% of the total mass of the casting fly ash mixture and the casting regenerated ash mixture, and the casting dedusting ash mixture comprises casting dedusting ash, desulfurized gypsum, slaked lime and slag according to the mass ratio of (20-50): (15-25): (10-20): (15-40), and the casting regenerated ash mixture comprises casting regenerated ash and steel slag according to the mass ratio of (0-60): (40-100). The casting waste ash, the desulfurized gypsum, the steel slag and other raw materials are mixed, and the exciting agent, the inorganic aluminate and other auxiliary materials are added to prepare the cementing material, and the performance of the prepared cementing material meets the performance requirements of national standard 325 Portland cement.
本发明涉及建筑材料技术领域，具体涉及一种利用铸造废灰制备的胶凝材料。一种利用铸造废灰制备的胶凝材料，包括80‑85份铸造除尘灰混合料、15‑20份铸造再生灰混合料、占铸造除尘灰混合料和铸造再生灰混合料总质量1‑4％的激发剂以及占铸造除尘灰混合料和铸造再生灰混合料总质量5‑10％的无机铝酸盐；铸造除尘灰混合料包括质量比为(20‑50):(15‑25):(10‑20):(15‑40)的铸造除尘灰、脱硫石膏、消石灰、矿渣，铸造再生灰混合料包括质量比为(0‑60):(40‑100)的铸造再生灰和钢渣。本发明将铸造废灰与脱硫石膏、钢渣等原料混合后并通过添加激发剂和无机铝酸盐等辅料制备得到了一种胶凝材料，所制备的胶凝材料的性能与国标325硅酸盐水泥性能要求。
