Mineral admixture for concrete and preparation method thereof
The invention discloses a mineral admixture for concrete and a preparation method thereof. The mineral admixture comprises the following components in parts by weight: 50-220 parts of mixing plant waste slurry water, 20-100 parts of mixing plant solid waste, 20-150 parts of industrial solid waste, 0.3-1.5 parts of a grinding aid and 0.3-1.5 parts of a dispersing agent. The mineral admixture prepared by the preparation method disclosed by the invention can replace part of cementing materials used in a concrete preparation process while realizing reutilization of various solid waste resources, so that the cost of concrete raw materials is reduced, and the durability of concrete is improved.
本发明公开了一种混凝土用矿物掺合料及其制备方法。该矿物掺合料包括以下重量份的组分：搅拌站废浆水50～220份、搅拌站固废20～100份、工业固废20～150份、助磨剂0.3～1.5份，以及分散剂0.3～1.5份。本发明制备得到的矿物掺合料能在实现多种固废资源再利用的同时，替代混凝土制备过程中使用到的部分胶凝材料，降低混凝土原材料成本，提高混凝土耐久性。
