Method for preparing recycled concrete small hollow block by using waste red brick powder
The invention discloses a method for preparing a small recycled concrete hollow block by using waste red brick powder. The small recycled concrete hollow block comprises the following components in parts by weight: 8-15 parts of cement, 5-30 parts of red brick powder, 10-60 parts of recycled concrete aggregate A, 5-40 parts of recycled concrete aggregate B, 0-3.0 parts of an inorganic early strength agent and 0-2 parts of a water reducing agent. According to the method, the small hollow concrete block prepared from the waste red brick powder is high in early strength, and besides cement and additives, other materials in the formula are all recycled materials, so that the resource utilization rate of building solid wastes is high, the cost is low, and the method has important practical value.
本发明公开了一种利用废弃红砖磨粉料制备再生混凝土小型空心砌块的方法，包括如下重量份数的组成：水泥8‑15份，红砖磨粉料5‑30份，再生砼骨料A 10‑60份、再生砼骨料B 5‑40份、无机早强剂0‑3.0份、减水剂0‑2份。该方法使用了废弃的红砖磨粉料所制备的混凝土小型空心砌块早期强度高，且配方中除了水泥及添加剂，其它均为再生材料，即对建筑固废的资源化利用高，成本低，具有重要的实际价值。
