Recycled micro-powder concrete and preparation method thereof
The invention discloses regenerated micro powder concrete and a preparation method thereof. The preparation method comprises the following steps: S1, material selection: water, cement, sand, stone, a water reducing agent, silica fume and regenerated micro powder are included, and the regenerated micro powder comprises concrete regenerated micro powder (RCP) and brick powder (RBP); S2, ball milling: carrying out ball milling on the regenerated micro powder through a ball mill to obtain refined regenerated micro powder; S3, proportioning: respectively weighing the RCP and the RBP according to a ratio of 8: 2, and performing stirring to obtain a regenerated micro-powder mixture; S4, activating: adding an exciting agent into the regenerated micro-powder mixture, the adding amount of the exciting agent being 2%-5% of the mass of the regenerated micro-powder mixture, and obtaining an activated regenerated micro-powder mixture. The recycled micro-powder concrete can be prepared by utilizing the coagulation effect of the recycled micro-powder to replace part of cement, and has the advantages of improving the concrete performance, reducing the solid waste pollution, reducing the building energy consumption, saving the cost and the like.
本发明公开了一种再生微粉混凝土及其制备方法，包括以下步骤：S1：选料：包括水、水泥、砂、石、减水剂、硅灰和再生微粉，所述再生微粉包括混凝土再生微粉(RCP)和砖粉(RBP)；S2：球磨：通过球磨机对所述再生微粉球磨，获取细化再生微粉；S3：配比：按照8:2的比例分别称取所述RCP和RBP，搅拌后获得再生微粉混合料；S4：活化：向所述再生微粉混合料中加入激发剂，所述激发剂的添加量为再生微粉混合料质量的2％‑5％，获得活化再生微粉混合料。可利用再生微粉凝结作用制备成再生微粉混凝土，替换部分水泥，具备提高混凝土性能、减少固体垃圾污染、降低建筑能耗，节约成本等优点。
