Carbonized steel slag-nickel slag composite mineral admixture
The invention discloses a carbonized steel slag-nickel slag composite mineral admixture which comprises the following raw materials: 42-64 parts of carbonized steel slag, 16-20 parts of carbonized nickel slag, 10-30 parts of superfine fly ash and 10-25 parts of silica fume. The carbonized steel slag and the carbonized nickel slag are respectively formed by carbonizing steel slag or nickel slag, a carbonization additive and water, and the additive comprises redispersible latex powder and sodium bicarbonate in a weight ratio of 1: (2-4). The carbonized steel slag-nickel slag mineral admixture is small in particle size and large in specific surface area, the 7d activity index reaches 100-111%, the 28d activity index reaches 93-101%, the activity index of the carbonized steel slag-nickel slag mineral admixture is effectively improved, the production cost can be reduced while industrial metallurgical solid waste is consumed, and the effects of energy conservation and emission reduction are achieved.
本发明公开了一种碳化钢渣‑镍渣复合矿物掺合料，包括如下原料：碳化钢渣42‑64份，碳化镍渣16‑20份、超细粉煤灰10‑30份及硅灰10‑25份。碳化钢渣和碳化镍渣分别由钢渣或镍渣、碳化外加剂和水碳化而成，外加剂包括重量比1:2‑4的可再分散性乳胶粉及碳酸氢钠。本发明的碳化钢渣‑镍渣矿物掺合料的粒度小，比表面积大，7d活性指数达到100‑111％，28d活性指数达到93‑101％，有效提高了碳化钢渣‑镍渣矿物掺合料的活性指数高，在消纳工业冶金固废的同时还能降低生产成本，具有节能减排的效果。
