C80 low-carbon high-strength recycled coarse aggregate concrete material
The invention discloses a C80 low-carbon high-strength recycled coarse aggregate concrete material. The concrete comprises the following components in parts by weight: 520-580 parts of slag powder, 50-100 parts of silica fume, 700-850 parts of fine sand, less than or equal to 750 parts of gravel and less than or equal to 750 parts of recycled coarse aggregate. In the technical scheme, the recycled coarse aggregate is used for partially or completely replacing the gravel, so that on one hand, the use of the natural coarse aggregate can be reduced, the problem of non-renewable resource shortage is relieved, and the ecological environment is improved; on the other hand, the problems of land occupation and environmental pollution caused by waste construction waste can be solved.
本申请公开了C80低碳高强再生粗骨料混凝土材料。该混凝土按照重量份包含以下组分：按照重量份包含以下组分：矿渣粉520‑580份、硅灰50‑100份、细砂700‑850份、碎石≦750份和再生粗骨料≦750份。本技术方案中，采用再生粗骨料部分或全部替代碎石，一方面可以减少天然粗骨料的使用，缓解不可再生资源短缺问题，改善生态环境；另一方面可以解决废弃建筑垃圾占地和环境污染的问题。
