Method for producing concrete composite mineral admixture
The invention discloses a method for producing a concrete composite mineral admixture, and relates to the technical field of composite mineral admixture manufacturing. A method for producing a concrete composite mineral admixture comprises the following steps that magnetic metal in a mixed slag raw material A is picked out through a magnetic separation method, and the mixed slag raw material A comprises 20-30 wt% of granulated blast furnace slag, 20-30 wt% of silica fume, 10-20 wt% of volcanic ash, 10-20 wt% of quartz powder and 2-5 wt% of a composite exciting agent; 2, the mixed slag raw material A is put into a vertical mill to be ground, after grinding is completed, a powdery slag raw material B is selected by a powder separator through a drying machine, and the particle diameter of the powdery slag raw material B ranges from 12 micrometers to 19 micrometers. According to the present invention, the large-scale application of the industrial waste residue-based admixture in the concrete means that the environmental pollution and the land resource waste of the industrial waste residue are reduced during the concrete production, and the use amount of the cement in the cementing material is reduced so as to indirectly reduce the environmental pollution caused by the cement production;
本发明公开了一种生产混凝土复合矿物掺合料的方法，涉及复合矿料掺合料制造技术领域。一种生产混凝土复合矿物掺合料的方法，步骤如下：运用磁选法将混合矿渣原料A中的磁性金属挑选出来，混合矿渣原料A包括粒化高炉矿渣20‑30wt％、硅灰20‑30wt％、火山灰10‑20wt％、石英粉10‑20wt％和复合激发剂2‑5wt％；步骤二：将混合矿渣原料A投入到立磨机中进行研磨，研磨完成后通过烘干机烘干在由粉选机选择出粉状矿渣原料B，粉状矿渣原料B的颗粒直径大小为12‑19μm之间。本发明以工业废渣为主的掺合料在混凝土中的大量应用,首先它意味着混凝土的生产降低了工业废渣自身的环境污染及土地资源浪费其次它减少了胶结材中水泥的用量而间接地减少了由于生产水泥而导致的环境污染。
