Green concrete with low carbon emission and ultra-high performance
The invention discloses green concrete with low carbon emission and ultra-high performance. The concrete is prepared from the following components in parts by weight: 300 to 1000 parts of mineral powder, 50 to 120 parts of fly ash, 50 to 120 parts of silica fume, 1 to 300 parts of Portland cement, 600 to 750 parts of quartz sand and 500 to 1100 parts of quartz stone. In the technical scheme, according to the green ultra-high performance concrete material with low carbon emission, a small amount of Portland cement is used for replacing an alkaline exciting agent, quartz stone is used for reducing the use amount of a gel material, nano-cellulose is used for enhancing the workability and fluidity of freshly mixed concrete, and steel fibers are used for enhancing the basic performance of the concrete; compared with common alkali-activated concrete, the alkali-activated concrete provided by the invention can greatly reduce the use amount of the alkali activator, and has the characteristics of low construction cost, high early strength, environmental protection, less carbon emission and the like.
本申请公开了低碳排放量绿色超高性能的混凝土。该混凝土按照重量份包含以下组分：矿粉300‑1000份、粉煤灰50‑120份、硅灰50‑120份、硅酸盐水泥1‑300份、石英砂600‑750份和石英石500‑1100份。本技术方案中，本发明所述的低碳排放量绿色超高性能混凝土材料，使用少量硅酸盐水泥替代碱性激发剂，使用石英石降低凝胶材料的用量，使用纳米纤维素增强新拌混凝土的和易性和流动性，使用钢纤维增强混凝土基本性能，相较于普通碱激发混凝土，可大幅降低碱性激发剂的用量，具有工程造价低，早期强度高，绿色环保，碳排放量少等特点。
