Early-strength high-toughness ultra-high performance concrete as well as preparation method and application thereof
The invention relates to early-strength high-toughness ultra-high performance concrete as well as a preparation method and application thereof. The early-strength high-toughness ultra-high performance concrete is prepared from the following components in parts by mass: 580 to 620 parts of cement, 90 to 100 parts of silica fume, 230 to 250 parts of quartz powder, 6 to 11 parts of a water reducing agent, 110 to 125 parts of an early strength agent, 180 to 195 parts of water, 475 to 495 parts of fine quartz sand, 630 to 660 parts of coarse quartz sand, 105 to 130 parts of basalt aggregate and 30 to 45 parts of steel fiber. Compared with the prior art, cement hydration is promoted through the silicate early strength agent, and the early strength is improved; by optimizing the mineral aggregate composition of the cement-based material, the strength and durability are improved; by adding the basalt coarse aggregate, the problem of environmental pollution is relieved, the cost is reduced, and safe recycling is promoted; the early-strength high-toughness ultra-high performance concrete disclosed by the invention is compact in structure and has excellent compactness and permeability resistance.
本发明涉及一种早强高韧性超高性能混凝土及其制备方法与应用，所述早强高韧性超高性能混凝土包括以下质量份的各组分：水泥580～620份、硅灰90～100份、石英粉230～250份、减水剂6～11份、早强剂110～125份、水180～195份、细石英砂475～495份、粗石英砂630～660份、玄武岩骨料105～130份和钢纤维30～45份。与现有技术相比，本发明通过硅酸盐类早强剂促进水泥水化，提升早期强度；通过优化水泥基材料矿料组成，提高强度和耐久；通过添加玄武岩粗骨料，缓解环境污染问题，减少成本，促进安全回收利用；本发明的早强高韧性超高性能混凝土结构致密，具有优异的致密性和抗渗透性能。
