Mineral admixture containing low-silicon dolomite powder and preparation method thereof
The invention discloses a mineral admixture containing low-silicon dolomite powder and a preparation method thereof, and the preparation method specifically comprises the following steps: 1, collecting waste concrete, removing impurities, and crushing the concrete by using crushing equipment to form set cement particles with the particle size of 5-20 mm; the invention relates to the technical field of building materials. According to the mineral admixture containing the low-silicon dolomite powder and the preparation method of the mineral admixture, the low-silicon dolomite powder is added and used for replacing part of cement, the cost of concrete is reduced, meanwhile, the performance of the concrete can be improved, and the compressive strength, impermeability and durability of the concrete are improved; the concrete curing time is shortened, the working performance of the concrete can be improved, and the flowability and pumpability of the concrete are improved.
本发明公开了含有低硅白云石粉的矿物掺合料及其制备方法，具体包括以下步骤：步骤一、收集废弃的混凝土，去除杂物，利用破碎设备对混凝土进行粉碎，形成粒径大小为5‑20mm水泥石颗粒；本发明涉及建筑材料技术领域。该含有低硅白云石粉的矿物掺合料及其制备方法，通过低硅白云石粉的加入，用于替代部分水泥，降低混凝土的成本，同时可以改善混凝土的性能，提高混凝土的抗压强度、抗渗性和耐久性，白云石粉可以促进混凝土的早期强度发展，缩短混凝土的养护时间，还可以改善混凝土的工作性能，提高混凝土的流动性和可泵性。
