Preparation process of high-strength recycled concrete
The invention belongs to the field of recycled concrete, and particularly relates to a preparation process of high-strength recycled concrete, and the high-strength recycled concrete is prepared from the following raw materials in parts by weight: 290-300 parts of cement, 195-210 parts of water, 450-500 parts of recycled aggregate, 400-410 parts of sand, 100-130 parts of admixture, 8-9 parts of penetrant and 5-7 parts of water reducing agent. After the notches in the fixed filter screen and the movable filter screen are staggered and fixed, a closed filter screen is formed, the recycled aggregates are placed in the closed filter screens one by one, and part of the recycled aggregates can roll along with rotation of the driving ring, so that the recycled aggregates are more easily and comprehensively cleaned, the cleaning efficiency is improved, and the defects that in a traditional method, the cleaning efficiency is higher, and the cost is lower are overcome. The problems that all recycled aggregates are stacked together, the recycled aggregates stacked in the middle area are not prone to being cleaned, and the cleaning efficiency is low are solved.
本发明属于再生混凝土领域，具体的说是一种高强度再生混凝土制备工艺，高强度再生混凝土由下列重量份的原料组成：水泥为290‑300份、水为195‑210份、再生骨料450‑500份、砂为400‑410份、掺和料为100‑130份、渗透剂为8‑9份、减水剂为5‑7份；固定滤网和活动滤网上的缺口错开并固定后，组成一个闭合的滤网，再生骨料被分别放置在一个个闭合滤网中，且部分再生骨料随着驱动环旋转时自身也会发生滚动，使得再生骨料更容易被全面清洗，提高了清洗效率，改善了传统方法中，所有的再生骨料都堆积在一起，堆集在中间区域的再生骨料不易被清洗到，清洗效率较低的问题。
