Recycling method of concrete waste residues from mixing plant
The invention belongs to the technical field of resource recycling, and particularly discloses a recycling method of concrete waste residues from a mixing plant. The recycling method comprises the following steps: mixing the concrete waste residues with a cementing material, a high-efficiency water reducing agent, an expanding agent, an early strength agent, a water-retaining agent and other components according to a predetermined mass ratio to prepare a building material. The building material has high early strength, workability, micro-expansion performance and water dispersion resistance, and can be used as an early-strength micro-expansion grouting material. According to the recycling method, sediment waste residues generated after tank truck flushing in the concrete mixing plant are recycled and then subjected to simple coarse grinding treatment so that the sediment waste residues can be directly utilized, treatment such as sand and stone separation, sedimentation, filtering, drying and grinding of cement paste in the sediment waste residues is not needed, the recycling method is simple in process and low in cost, the effect of recycling resources can be achieved at the lowest cost, the environmental pollution is reduced, and the preparation method of an early-strength micro-expansion grouting material, which is cheaper, is also provided.
本发明属于资源回收再利用技术领域，尤其公开了一种源于搅拌站的混凝土废渣的回收利用方法，该回收利用方法即将混凝土废渣与胶凝材料、高效减水剂、膨胀剂、早强剂、保水剂等成分按照预定质量比例混合，制备获得一种建筑材料。该建筑材料具有良好的早期强度、工作性、微膨胀性能和抗水分散性能，可以作为一种早强微膨胀灌浆料使用。该回收利用方法可将混凝土搅拌站在冲洗罐车后的沉淀废渣回收后进行简单的粗磨处理即可直接利用，而无需进行砂石分离，及沉淀、过滤、烘干、粉磨其中的水泥浆等处理，回收利用方法工艺简单，能够以最低成本达到资源回收再利用的效果，不仅减少了环境污染，而且也提供了一种更为低廉的早强微膨胀灌浆料的制备方法。
