Industrial solid waste cement for heavy metal pollution treatment
The invention discloses industrial solid waste cement for heavy metal pollution treatment. The industrial solid waste cement is prepared from the following raw materials in parts by mass: 52-70 parts of blast furnace water-quenched slag, 12-26 parts of steel slag, 17-18 parts of desulfurized gypsum, 1-4 parts of auxiliary materials, 2-5 parts of cement clinker and 1-3 parts of a water reducing agent. Main components of the cement comprise blast furnace water-quenched slag, steel slag, desulfurized gypsum and auxiliary materials, more than 90% of the components come from industrial solid wastes, and main components in traditional cement are used as the auxiliary materials of the solid waste cement. Compared with traditional cement production, the production process of the industrial solid waste cement has the advantages that production energy consumption is remarkably reduced, and environmental pollution is caused.
本发明公开了一种针对重金属污染治理的工业固废水泥，包括以下质量份的原料：高炉水淬渣为52‑70份、钢渣为12‑26份、脱硫石膏为17‑18份、1‑4份辅料、2‑5份水泥熟料、1‑3份减水剂。该水泥的主要成分为高炉水淬渣、钢渣、脱硫石膏、辅料，成分中90％以上来源于工业固体废弃物，将传统水泥中的主要成分作为该种固废水泥的辅料。相较于传统水泥生产来说，该种工业固废水泥的生产过程具有显著降低生产能源消耗和带来环境污染问题。
