All-solid-waste-based concrete composite mineral admixture and preparation method thereof
Belonging to the technical field of admixture preparation, the invention discloses a full solid waste based concrete composite mineral admixture, which comprises the following components by mass: 50-70 parts of slag, 10-20 parts of metal tailings, 0-10 parts of fly ash, 5-20 parts of steel slag, 0-5 parts of ferronickel slag, 0-5 parts of lithium slag, 0-5 parts of kiln dust, 0.5-5 parts of a mineral activity activator, and 0.05-0.5 part of a grinding aid. According to the invention, the problem of treatment of tailings and metallurgical solid wastes is effectively solved, the contradiction of shortage of concrete mineral admixture sources in China is relieved, and unification of economic and social benefits is facilitated.
本发明公开了一种全固废基混凝土复合矿物掺合料，属于掺合料制备技术领域，包括以下按质量配比的组分：矿渣50‑70份，金属尾矿10‑20份，粉煤灰0‑10份，钢渣5‑20份，镍铁渣0‑5份，锂渣0‑5份，窑灰0‑5份，矿物活性激发剂0.5‑5份，助磨剂0.05‑0.5份，本发明公开的一种有效解决尾矿及冶金固废处理难题，缓解我国混凝土矿物掺合料来源匮乏的矛盾，有助于实现经济和社会效益统一。
