Production method for producing concrete composite mineral admixture by utilizing industrial waste residues
The invention discloses a production method for producing a concrete composite mineral admixture by utilizing industrial waste residues. The composite mineral admixture is composed of the following components in parts by weight: 30%-50% of steel mill granulated blast furnace slag, 10%-30% of manganese alloy slag, 12%-20% of power plant slag, 14%-22% of power plant fly ash, 3%-7% of power plant desulfurized gypsum and 1%-2% of a composite chemical strength excitant. The production method of the composite mineral admixture comprises the following steps: S1, preparing materials; step S2, warehousing; s3, mixing the materials; s4, grinding; s5, screening; and S6: homogenizing. The high-performance concrete composite mineral admixture produced according to the production method provided by theinvention has the advantages that the comprehensive cost is greatly reduced, the construction is simple, a large amount of industrial waste residues are used, the high hydration heat of concrete is compensated, the sulfate corrosion resistance is realized, the workability of the concrete is improved, the durability of the concrete is improved, and the pumpability of the concrete is improved. And the national requirements of energy conservation, environmental protection, low carbon and resource recycling are met.
本发明公开了一种利用工业废渣生产混凝土复合矿物掺合料的生产方法，复合矿物掺合料由以下重量份的成分组成：钢厂粒化高炉矿渣30％‑50％、锰合金矿渣10％‑30％、电厂炉渣12％‑20％、电厂粉煤灰14％‑22％、电厂脱硫石膏3％‑7％和复合化学强度激发剂1％‑2％；复合矿物掺合料的生产方法包括如下步骤：步骤S1：备料；步骤S2：入库；步骤S3：混料；步骤S4：粉磨；步骤S5：筛选；步骤S6：均化。根据本发明提供的生产方法生产的高性能混凝土复合矿物掺合料，其综合成本较大幅度的降低，施工简单，并且大量使用工业废渣，弥补了混凝土水化热高，抗硫酸盐侵蚀，增加混凝土和易性，提高混凝土耐久性，提高混凝土的泵送性。达到国家要求的节能、环保、低碳、资源再生利用。
