Low-carbon high-performance recycled concrete and preparation method thereof
The invention discloses low-carbon high-performance recycled concrete and a preparation method thereof. The low-carbon high-performance recycled concrete is prepared from the following raw material components: 1075 to 1266 parts of recycled coarse aggregate, 450 to 656 parts of fine aggregate, 280 to 320 parts of cement, 10 to 20 parts of an exciting agent, 30 to 70 parts of rice hull ash, 40 to 140 parts of diatomite, 30 to 60 parts of red mud, 60 to 90 parts of aluminum silicate fiber, 40 to 70 parts of coconut fiber, 50 to 80 parts of bamboo fiber, 5 to 10 parts of a water reducing agent and 200 to 290 parts of water. According to the low-carbon high-performance recycled concrete disclosed by the invention, natural aggregate is replaced by the recycled aggregate and the lithium tailings, so that the recycling of building and industrial solid wastes is facilitated, the treatment cost of the solid wastes and the burden of the solid wastes on the environment are reduced, the resource utilization of the solid wastes is promoted, the material cost of the building is greatly reduced, and a large amount of gravel materials are saved; the phenomenon that natural gravel resources are insufficient is relieved, and cyclic utilization of the resources is achieved.
本发明公开一种低碳型高性能再生混凝土及其制备方法，包括原材料组分如下：再生粗骨料1075‑1266份、细骨料450‑656份、水泥280‑320份、激发剂10‑20份、稻壳灰30‑70份、硅藻土40‑140份、赤泥30‑60份、硅酸铝纤维60‑90份、椰子纤维40‑70份、竹纤维50‑80份、减水剂5‑10份、水200‑290份。本发明的低碳型高性能再生混凝土，利用再生骨料和锂尾矿取代天然骨料，利于建筑与工业固废的再利用，降低固废的处理成本及其对环境造成的负担，促进固废的资源化利用，极大地降低了建筑的材料成本，而且节省了大量的砂石材料，缓解了天然砂石资源不足的现象，实现了资源的循环利用。
