Dry-mixed mortar prepared by dry treatment of all-concrete recycled aggregate and preparation method of dry-mixed mortar
The invention provides dry-mixed mortar prepared by dry-process treatment of all-concrete recycled aggregate and a preparation method of the dry-mixed mortar, and relates to the technical field of building materials. The dry-mixed mortar is prepared from the following components in parts by weight: 10 to 20 parts of cement, 3 to 10 parts of active filler, 75 to 85 parts of recycled aggregate, 0.01 to 0.06 part of a water-retaining thickening agent, 0.002 to 0.006 part of an air entraining agent, 0.025 to 0.075 part of a water reducing agent and 1 to 2 parts of a lubricating agent. In the technical scheme provided by the invention, the main raw material is the recycled aggregate obtained from the concrete construction waste, and the preparation method of the recycled aggregate does not need drying and wet modification, and is simple in process and low in energy consumption. And other aggregates such as natural sand do not need to be doped, so that the utilization rate of the recycled concrete solid waste can be greatly increased, the recycled concrete is more environment-friendly, and the limitations of shortage of natural sand resources and difficulty in mining are avoided. The other raw materials are conventional products in the market, are easy to obtain and are low in cost. After the prepared dry-mixed mortar is sealed and stored for 30 days, the product character is not obviously changed.
本发明提供了一种干法处理全混凝土再生骨料制备的干混砂浆及其制备方法，涉及建筑材料技术领域。所述干混砂浆按重量份数计，包括以下组分：水泥10‑20份，活性填料3‑10份，再生骨料75‑85份，保水增稠剂0.01‑0.06份，引气剂0.002‑0.006份、减水剂0.025‑0.075份，润滑剂1‑2份。本发明提供的技术方案中，所用主要原料为混凝土建筑垃圾得到的再生骨料，再生骨料的制备方法无需烘干及湿法改性，工艺简单、能耗低。而且无需再掺加天然砂等其他骨料，不仅能够大幅提升再生混凝土固废的利用率，更加绿色环保，还避免了天然砂资源短缺及开采不易的限制。所用的其他原料均为市面常规产品，原料易取、成本低廉。制备得到的干混砂浆经30天密封储存后，产品性状也无明显变化。
