Machine-made mountain sand efficient composite mineral admixture and preparation device thereof
The invention provides a high-efficiency composite mineral admixture for machine-made mountain sand. The high-efficiency composite mineral admixture comprises the following raw materials in percentage by weight: 50-60% of gneiss powder; 15-25% of fly ash floating beads; 10-20% of quartz sand tailings; 6-10% of limestone powder; and a grinding aid accounting for 0.2-0.5% of the total weight of the gneiss powder, the fly ash floating beads, the quartz sand tailings and the limestone powder. According to the scheme, the fineness, the activity index and the fluidity ratio of the finally prepared composite mineral admixture can meet the requirements of conventional composite admixture products, the mortar fluidity can be improved, the machine-made hill sand and the industrial solid waste are adopted as raw materials, the cost is low, energy is saved, environment friendliness is achieved, and the composite mineral admixture can be used for improving the performance of concrete.
本发明提供一种机制山砂高效复合矿物掺合料，按重量百分数包括如下原料：片麻岩石粉50‑60％；粉煤灰漂珠15‑25％；石英砂尾矿10‑20％；石灰石粉6‑10％；以及占片麻岩石粉、粉煤灰漂珠、石英砂尾矿和石灰石粉总重量0.2‑0.5％的助磨剂。该方案最终实现制备的复合矿物掺合料细度、活性指数、流动度比能够满足常规复合掺合料产品要求，且能够提高砂浆流动度，且采用机制山砂及工业固体废弃物作为原料，成本低廉，节能环保，能够用于改善混凝土的性能。
