Composite mineral admixture and preparation method thereof
The invention belongs to the technical field of building materials, and relates to a mineral admixture, in particular to a composite mineral admixture and a preparation method thereof. The mineral admixture comprises the following components in parts by weight: 60-80 parts of limestone, 10-20 parts of kiln ash, 10-30 parts of steel slag, 5-10 parts of silica fume, 5-10 parts of an excitant and 5-10 parts of ZnO series ceramic particles, wherein the steel slag is steelmaking waste slag. According to the composite mineral admixture provided by the invention, chlorine dioxide and ZnO ceramic particles are added, limestone is used as a composite admixture, the activity index is high, the fluidity ratio is large, and the blended concrete has the advantages of high early strength, small contractibility and strong crack resistance, and has an industrial value.
本发明属于建筑材料技术领域，涉及一种矿物掺合料，具体涉及一种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：石灰石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，钢渣是炼钢废弃渣。本发明提供的复合矿物掺合料通过二氧化氯、ZnO系陶瓷颗粒的添加，使石灰石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。
