Ferronickel slag and steel slag composite powder high-grade concrete admixture and preparation method thereof
The invention discloses a ferronickel slag and steel slag composite powder high-grade concrete admixture and a preparation method thereof. The ferronickel slag and steel slag composite powder high-grade concrete admixture comprises the following components by mass: 20-50 parts of blast furnace ferronickel slag, 10-30 parts of submerged arc furnace ferronickel slag, 5-20 parts of steel slag, 25-35parts of fly ash, 5-15 parts of desulfurized gypsum powder, 0.1-2 parts of a flow aid and 0.1-0.3 part of a grinding aid. The ferronickel slag and steel slag composite powder high-grade concrete admixture has high fluidity and high activity, and does not swell easily after encountering water.
本发明公开的一种镍铁渣钢渣复合粉高级混凝土掺合料及制备方法，包括质量份数如下的组分：20‑50份高炉镍铁渣、10‑30矿热炉镍铁渣、5‑20份钢渣、25‑35份粉煤灰、5‑15份脱硫石膏粉、0.1‑2份助流剂、0.1‑0.3份助磨剂，流动度高、活性高，遇水不易溶胀。
