Environment-friendly concrete and preparation method thereof
The invention discloses environment-friendly concrete and a preparation method thereof, relates to the technical field of concrete, and solves the problem that the compressive strength of recycled concrete waste is greatly reduced in the long-term use process due to the fact that many micro-cracks exist on the surface of the recycled concrete waste. The environment-friendly concrete is prepared from the following components in parts by weight: 180 to 220 parts of Portland cement; 170 to 180 parts of water; 740 to 760 parts of medium sand; 800 to 860 parts of broken stone; 210 to 240 parts of recycled concrete waste materials; 70 to 80 parts of fly ash; 160 to 190 parts of mineral powder; 4-5 parts of a water reducing agent; 2 to 3 parts of a retarder; 8 to 12 parts of a filling reinforcingmaterial; 10 to 16 parts of diatomite; 25 to 35 parts of urea; and 8-10 parts of soybean seed coat powder. The environment-friendly concrete disclosed by the invention is relatively low in carbonization speed in long-term application, and good and stable compressive strength can be integrally maintained.
本发明公开了一种绿色环保混凝土及其制备方法，涉及混凝土技术领域，解决了因再生混凝土废料表面存在较多微裂缝，而导致其在长时间使用过程中的抗压强度会大大降低。一种绿色环保混凝土，其包括如下重量份数的组分：硅酸盐水泥180‑220份；水170‑180份；中砂740‑760份；碎石800‑860份；再生混凝土废料210‑240份；粉煤灰70‑80份；矿粉160‑190份；减水剂4‑5份；缓凝剂2‑3份；填充强化料8‑12份；硅藻土10‑16份；尿素25‑35份；大豆种皮粉8‑10份。本发明中的绿色环保混凝土在长时间应用中的碳化速度较慢，整体能够保持良好稳定的抗压强度。
