Method for preparing recycled concrete from waste concrete blocks
The invention belongs to the technical field of waste concrete utilization, and particularly relates to a method for preparing recycled concrete from waste concrete blocks, which comprises the following specific steps: S1, grinding the waste concrete: crushing the waste concrete into small blocks through a crusher or an artificial heavy hammer, the small blocks of waste concrete are placed in extrusion type crushing equipment to be extruded and crushed; s2, cleaning the waste concrete particles; and S3, mixing the raw materials. The waste concrete is subjected to repeated particle size reduction treatment such as crushing and grinding, so that the waste concrete is treated into extremely small particles, the defects such as internal vacancy and stress do not exist, and the overall structural strength of the prepared recycled concrete is relatively good; by using the glass fibers and the stones, the overall structural strength of the recycled concrete is further improved, and dust and other impurities on the concrete chippings are removed in a cleaning mode and are prevented from affecting the overall structural strength of the recycled concrete.
本发明属于废弃混凝土利用技术领域，具体为一种利用废弃混凝土块制备再生混凝土的方法，该利用废弃混凝土块制备再生混凝土的方法的具体步骤如下：S1：将废弃混凝土磨碎：废弃混凝土通过破碎机或人工重锤破碎为小块状，将小块状废弃混凝土置于挤压式粉碎设备中挤压粉碎；S2：对废弃混凝土粒清理；S3：混合原料。通过将废弃混凝土采用破碎、研磨等多次减小粒径化处理，使得废弃混凝土被处理为极小的颗粒状，不存在内部空缺、应力等缺陷，使得制成的再生混凝土整体结构强度较好；通过玻璃纤维及石子的使用，进一步提高再生混凝土整体结构强度，通过清理的方式，除去混凝土碎屑上的灰尘等杂质，避免其影响再生混凝土整体结构强度。
