Preparation method of environment-friendly water-saving recycled concrete
The invention discloses a preparation method of environment-friendly water-saving recycled concrete. The method comprises: weighing the following raw materials in parts by weight: 100-125 parts of coarse aggregate, 30-40 parts of fine aggregate, 20-30 parts of recycled aggregate, 30-35 parts of cement, 8-12 parts of fly ash, 3-5 parts of quartz sand, 4-7 parts of perlite, 6-12 parts of magnesium oxide, 2-6 parts of lubricating grease, 2-8 parts of talcum powder, 5-10 parts of water glass, 7-15 parts of sodium hexametaphosphate, 3-6 parts of a leveling agent, 4-8 parts of stearic acid and 15-18parts of water; pouring the recycled aggregate, the fly ash and the quartz sand into a stirrer, stirring and mixing, and spraying tap water to the surface of the mixture to completely wet the surfaceof the mixture. According to the invention, the production raw materials of concrete are subjected to grinding treatment, so that the quality during later processing can be guaranteed; a water-savingmaterial is added in the concrete preparation process, so that the environmental protection performance of the concrete can be improved; and waste materials can be subjected to cyclic processing treatment in the building construction process, so that resources are effectively saved, and the utilization rate is increased.
本发明公开了一种环保节水型再生混凝土制备方法，首先称取以下重量份的原料：粗集料100‑125份、细集料30‑40份、再生集料20‑30份、水泥30‑35份、粉煤灰8‑12份、石英砂3‑5份、珍珠岩4‑7份、氧化镁6‑12份、润滑脂2‑6份、滑石粉2‑8份、水玻璃5‑10份、六聚偏磷酸钠7‑15份、流平剂3‑6份、硬脂酸4‑8份和水15‑18份；将再生集料、粉煤灰和石英砂倒入搅拌机中进行搅拌混合，再向混合物的表面喷洒自来水，使得混合物的表面全部湿润。本发明通过对混凝土的生产原料进行碾磨处理，可以保证后期加工时的质量，而且混凝土制备过程中添加了节水型材料可以增加混凝土的环保性能，在建筑施工过程中可对废弃的废料进行循环加工处理，有效节约了资源，提高了利用率。
