Novel superfine steel slag powder concrete formula
The invention provides a novel superfine steel slag powder concrete formula, and relates to the technical field of concrete production. The novel superfine steel slag powder concrete formula is prepared from the following components in parts: 150 to 280 parts of steel slag powder, 90 to 180 parts of slag powder, 60 to 90 parts of desulfurized gypsum, 140 to 150 parts of water, 900 to 1000 parts of waste rock aggregate, 750 to 800 parts of tailing sand and 7 to 9 parts of a water reducing agent. By crushing and reutilizing the steel slag, the superfine steel slag powder can replace 40%-60% of S95 slag micro powder and is directly applied to cement and concrete, and compared with the S95 slag micro powder, the product strength is not reduced, the water demand is reduced, the working performance is optimized and improved, and the stability is good; compared with common concrete, the superfine steel slag powder concrete has the advantages that the strength of the superfine steel slag powder concrete in each stage is higher than that of the common concrete, and the superfine steel slag powder concrete has a remarkable cost advantage compared with the common concrete, so that the problem of short supply of superfine slag powder is solved, a large amount of steel slag can be utilized, the ecological environment is improved, and the green cycle development of iron and steel enterprises is promoted.
本发明提供一种新型超细钢渣粉混凝土配方，涉及混凝土生产技术领域。该一种新型超细钢渣粉混凝土配方，由以下份数成分组成：钢渣粉150‑280份、矿渣粉90‑180份、脱硫石膏60‑90份、水140‑150份、废石骨料900‑1000份、尾矿砂750‑800份、减水剂7‑9份。通过对于钢渣的破碎再利用，使用超细钢渣粉可以替代40％‑60％的S95矿渣微粉，直接应用于水泥和混凝土中，与S95矿渣微粉相比，产品强度不降低、需水量降低、工作性能得到优化提高，安定性良好，超细钢渣粉混凝土与普通混凝土相比各期龄强度均高于普通混凝土，且超细钢渣粉混凝土较普通混凝土有显著的成本优势，既解决了矿渣微粉紧俏的问题，又能够大量利用钢渣，改善生态环境，促进钢铁企业绿色循环发展，一举多得。
