Cement-free low-carbon ultra-high performance concrete
The invention discloses a cement-free low-carbon ultra-high performance concrete. The low-carbon ultra-high performance concrete comprises the following components: 500-800 kg/m < 3 > of blast furnace slag powder, 150-300 kg/m < 3 > of silica fume, 80-200 kg/m < 3 > of fly ash, 80-200 kg/m < 3 > of slaked lime powder and 900-1300 kg/m < 3 > of quartz sand. In the technical scheme, the cement-free low-carbon ultra-high performance concrete uses industrial solid wastes such as blast furnace slag powder, silica fume and fly ash to completely replace traditional Portland cement, is doped with slaked lime powder as an auxiliary gel material, has the characteristics of absorbing carbon dioxide and improving the hydration rate, and has the characteristics of low construction cost, high early strength, environmental friendliness, high strength, high strength, high strength and the like. Carbon emission is low, and the like.
本申请公开了不含水泥的低碳超高性能混凝土。该低碳超高性能混凝土，包含以下组分：高炉矿渣粉500‑800kg/m3、硅灰150‑300kg/m3、粉煤灰80‑200kg/m3、熟石灰粉80‑200kg/m3、石英砂900‑1300kg/m3。本技术方案中，不含水泥的低碳超高性能混凝土，使用工业固体废弃物高炉矿渣粉、硅灰和粉煤灰等完全替代传统硅酸盐水泥，掺入熟石灰粉作为辅助凝胶材料，可起到吸收二氧化碳，提高水化率的特点，具有工程造价低，早期强度高，绿色环保，碳排放量少等特点。
