Multi-solid-waste coupled Portland cement and preparation method thereof
The invention relates to multi-solid-waste coupled Portland cement and a preparation method thereof, the multi-solid-waste coupled Portland cement comprises the following raw materials by weight: 120-160 parts of high silicon iron tailings, 100-120 parts of fly ash, 300-400 parts of barren rock, 200-220 parts of limestone, 30-40 parts of slag, 30-40 parts of carbide slag, 120-150 parts of desulfurized gypsum, 10-20 parts of clay, 20-40 parts of water, 5-15 parts of a chemical activator and 3-5 parts of a water reducing agent. A large amount of industrial waste can be consumed to produce the multi-solid-waste coupled Portland cement, so that environmental pollution can be reduced, and waste is turned into wealth; and the problems of iron tailing accumulation and the like are effectively solved. In addition, the supply problem of cement and other raw materials can be effectively relieved, and meanwhile the cost is saved.
本发明涉及一种多固废耦合硅酸盐水泥及其制备方法，包括以下重量份的原料：高硅铁尾矿120‑160份、粉煤灰100‑120份、废石300‑400份、石灰石200‑220份、矿渣30‑40份、电石渣30‑40份、脱硫石膏120‑150份、黏土10‑20份、水20‑40份、化学活化剂5‑15份、减水剂3‑5份，本发明能够大量消耗工业废弃物生产多固废耦合硅酸盐水泥，不仅可以减少环境污染，变废为宝；而且有效地解决铁尾矿堆积等问题。另外，本发明可以有效缓解水泥等原料的供给问题，同时节约成本。
