Solid-waste-based iron-rich high-belite sulphoaluminate cement clinker and preparation method thereof
The invention discloses a solid-waste-based iron-rich high-belite sulphoaluminate cement clinker and a preparation method thereof. The raw materials are 100% of industrial solid waste residues and low-grade ore raw materials; the raw materials comprise, by weight, 50-55% of a calcium raw material; 20-30% of a low-aluminum raw material; 10-15% of a sulfur raw material; 5-10% of an iron raw material; 0.5 to 1.0 part of an additive; the clinker is prepared from the following minerals in percentage by weight: 56 to 60 percent of a-C2S mineral, 20 to 26 percent of # imgabs0 # mineral, 15 to 18 percent of C4AF mineral and 1 to 2 percent of f-CaSO4 mineral. According to the clinker disclosed by the invention, low-grade raw materials or industrial solid wastes with lower grade and lower price are used as the ingredient raw materials of the clinker to the maximum extent, the production cost is reduced, and the burnability of the clinker is improved by regulating and optimizing the mineral composition of the clinker and the liquid phase content of the clinker, so that the performance of the clinker is closer to that of ordinary Portland cement.
本发明公开了一种固废基富铁高贝利特硫铝酸盐水泥熟料及其制备方法，所用原料100％采用工业固体废渣和低品位矿石原料；原料配比的重量百分比为：钙质原料50‑55％；低铝质原料20‑30％；硫质原料10‑15％；铁质原料5‑10％；添加剂0.5‑1.0；熟料具有如下重量百分比矿物组成：à‑C2S矿物含量56‑60％，#imgabs0#矿物含量20‑26％，C4AF矿物含量15‑18％，f‑CaSO4矿物含量1‑2％。本发明熟料的配料原料最大限度使用品位更低、价格更低的低品位原料或者工业固废，降低生产成本，并通过对熟料矿物组成和熟料液相含量的调控和优化，改善了熟料易烧性，使熟料的性能更接近于普通硅酸盐水泥的性能。
