Green recycled aggregate reinforced concrete
The invention provides green recycled aggregate reinforced concrete, which is prepared from the following raw materials in parts by weight: 50 to 90 parts of cement, 60 to 120 parts of natural sand, 20 to 30 parts of limestone, 30 to 60 parts of rubber modified recycled aggregate, 3 to 8 parts of water reducing agent, 5 to 12 parts of waste rubber powder, 5 to 12 parts of chopped waste fiber and 30 to 50 parts of water, the particle size of the waste rubber powder is 1-3mm, and the length of the chopped fiber is 3-8cm. The waste rubber and the construction waste are processed into the recycled aggregate to partially or completely replace natural aggregate to prepare the recycled aggregate concrete, a large amount of construction waste can be effectively consumed, the city appearance and environmental sanitation can be improved, land occupation in the construction waste treatment process is reduced, and environmental pollution is relieved; meanwhile, the use of the recycled aggregate can reduce the demand of the concrete industry for natural gravel, thereby reducing the exploitation of the natural gravel and protecting the ecological environment.
本发明提供了绿色再生骨料增强混凝土，包括以下重量份的原料：水泥50‑90份，天然砂60‑120份，石灰岩20‑30份，橡胶改性再生骨料30‑60份，减水剂3‑8份，废弃橡胶粉5‑12份，短切废弃纤维5‑12份和水30‑50份，其中，天然砂的细度模数为2.1‑2.7，石灰岩粒径为10‑25mm，废弃橡胶粉的粒径为1‑3mm，短切纤维的长度为3‑8cm。本发明将废弃橡胶和建筑垃圾加工成再生骨料，部分或全部取代天然骨料制备再生骨料混凝土，能够有效的消耗大量建筑垃圾，改善市容和环境卫生，减少建筑垃圾处理过程中对土地的侵占，减轻环境污染；同时，再生骨料的使用，可以减少混凝土行业对天然砂石的需求量，从而减少对天然砂石的开采，保护生态环境。
