High-volume industrial solid waste composite Portland cement and preparation method thereof
The invention discloses high-volume industrial solid waste composite Portland cement and a preparation method thereof. The high-volume industrial solid waste composite Portland cement is prepared fromthe following raw materials in parts by weight: 85-115 parts of cement clinker, 5-6 parts of modified desulfurized fly ash and 0.05-0.1 part of a grinding aid, wherein the cement clinker is preparedfrom the following raw materials in parts by weight: 95-95.9 parts of a fired cement raw material and 4.1-5 parts of coal ash; the cement raw material is prepared from the following raw materials in parts by weight: 42.5-45 parts of carbide slag, 15-17 parts of iron tailings, 5-6 parts of fly ash, 35-40 parts of limestone and 2 parts of iron ore powder. According to the invention, industrial solidwastes such as carbide slag, iron tailings, desulfurized fly ash and the like are fully utilized, so that the preparation of the high-volume industrial solid waste composite Portland cement is realized, the problems that the industrial solid wastes such as carbide slag, iron tailings, desulfurized fly ash and the like occupy a large amount of land resources and cause serious environmental pollution are solved, and the utilization rate of the industrial solid wastes is improved.
本发明公开了大掺量工业固废复合硅酸盐水泥及其制备方法，它是由下述重量份的原料制成：水泥熟料85‑115份、改性脱硫灰5‑6份、助磨剂0.05~0.1份；所述水泥熟料是由下述重量份的原料制成：灼烧后的水泥生料95‑95.9份、煤灰4.1‑5份；所述水泥生料是由下述重量份的原料制成：电石渣42.5~45份、铁尾矿15~17份、粉煤灰5~6份、石灰石35~40份、铁矿粉2份。本发明充分利用电石渣、铁尾矿、脱硫灰等工业固废，实现了大掺量工业固废复合硅酸盐水泥的制造，解决了电石渣、铁尾矿、脱硫灰等工业固废占用大量土地资源并造成严重的环境污染问题，提高了工业固废利用率。
