Ultralow-carbon mineral admixture for typical iron alloy slag-based concrete and preparation method of ultralow-carbon mineral admixture
The invention discloses an ultra-low carbon mineral admixture for typical iron alloy slag-based concrete, and the ultra-low carbon mineral admixture comprises 25%-50% of low-carbon ferrochrome slag, 10%-35% of high-carbon ferrochrome slag, 15%-20% of silicomanganese slag, 10%-15% of blast furnace ferronickel slag and 10%-20% of water-quenched blast furnace granulated slag, and the invention further provides a preparation method of the ultra-low carbon mineral admixture for the typical iron alloy slag-based concrete. Typical iron alloy slag is subjected to secondary water quenching, crushing, screening and grinding, and finally ground slag powder is mixed to prepare the ultralow-carbon mineral admixture for the typical iron alloy slag-based concrete. The iron alloy smelting waste slag which is difficult to singly utilize is organically combined and applied to concrete production, so that the mechanical property of the concrete can be enhanced, the use amount of cement in the concrete is reduced, the emission of carbon dioxide is reduced, and the environmental problem caused by stacking of a large amount of iron alloy slag can be solved.
本发明公开了一种典型铁合金渣基混凝土用超低碳矿物掺合料，低碳铬铁渣25%~50%，高碳铬铁渣10%~35%，硅锰渣15%~20%，高炉镍铁渣10%~15%,水淬高炉粒化渣10%~20%，本发明还提供一种典型铁合金渣基混凝土用超低碳矿物掺合料的制备方法，具体包括以下步骤，将典型铁合金渣经二次水淬、破碎、筛选以及研磨，最终将研磨后的渣粉进行混合制得典型铁合金渣基混凝土用超低碳矿物掺合料。本发明通过将难以单一利用的铁合金冶炼废渣有机结合应用于混凝土生产，既能够增强混凝土的力学性能，降低混凝土中水泥使用量，减少二氧化碳排放，又可解决铁合金渣大量堆存带来的环境问题。
