Green concrete regeneration process and concrete
The invention discloses a green concrete regeneration process. The process comprises the following steps: S1, hammering waste concrete blocks to enable the diameter length of the hammered concrete blocks to be less than 50 mm, performing magnetic separation and screening, and removing contained metal impurities to prepare recycled aggregate; and the like. A concrete comprises, by weight, 95-105 parts of the waste concrete blocks, 18-22 parts of cement, 0.5-1.5 parts of nano-aluminum trioxide and the like. The regeneration process is scientific and reasonable, waste recycling can be achieved toa certain extent, environmental pollution and resource waste are reduced, the regeneration utilization rate is high, and high economic benefits and environmental protection benefits are achieved. Theconcrete prepared by the regeneration process is good in structural strength, eliminates or reduces micro-cracks in a concrete interface area, and improves the compactness of the concrete, thereby improving the strength of the concrete and the like.
本发明公开了一种绿色混凝土再生工艺，包括S1：锤击废弃混凝土块，使锤击后的混凝土块径长小于50mm，经过磁选筛分，除去含有的金属杂质，制得再生骨料等步骤；一种混凝土，包括废弃混凝土块95‑105重量份、水泥18‑22重量份、纳米三氧化铝0.5‑1.5重量份等原料。本发明再生工艺科学合理，能够一定限度的达到废物再利用，减少环境污染和资源浪费，再生利用率高，具有很高的经济效益和环保效益。利用本发明提供的再生工艺制备的混凝土结构强度好，消除或减少了混凝土界面区的微裂缝，提高混凝土密实性，从而提升该混凝土的强度等。
