Composite mineral admixture based on granite stone powder and preparation method thereof
The invention belongs to the technical field of building materials, and relates to concrete, in particular to a composite mineral admixture of granite stone powder and a preparation method thereof. The composite mineral admixture comprises the following components in parts by weight: 60-80 parts of granite powder, 10-20 parts of kiln ash, 10-30 parts of steel slag, 5-10 parts of silica fume, 5-10parts of an excitant and 5-10 parts of ZnO series ceramic particles, wherein the steel slag is silicon steel slag. By adding xanthate and ZnO series ceramic particles, the granite stone powder is usedas a composite mineral admixture, the activity index is high, the fluidity ratio is large, and the concrete mixed with the composite mineral admixture has the advantages of being high in early strength, small in contractibility and high in crack resistance and has an industrial value.
本发明属于建筑材料技术领域，涉及一种混凝土，具体涉及一种花岗岩石粉的复合矿物掺合料及其制备方法。其技术要点如下：按照重量份数计算，包括如下组分：花岗岩石粉60~80份，窑灰10~20份，钢渣10~30份，硅灰5~10份，激发剂5~10份和ZnO系陶瓷颗粒5~10份；其中，钢渣是硅钢渣。本发明提供的通过黄原酸盐、ZnO系陶瓷颗粒的添加，使花岗岩石粉作为一种复合矿物掺合料被利用，且活性指数高，流动度比大，其掺和的混凝土具有早期强度高，收缩性小，抗裂性强的优点，具有产业价值。
