Manganese slag-based ultrahigh-performance composite cementing material and concrete material
The invention discloses a manganese slag-based ultrahigh-performance composite cementing material and a concrete material. The cementing material comprises cement, electrolytic manganese slag, silica fume, limestone powder and calcium sulfate whiskers. According to the cementing material, solid waste materials such as the electrolytic manganese residues are adopted to replace part of cement, and the cement content is greatly reduced. The cementing material is matched with aggregate, multi-stage steel fibers and an additive to prepare a large-flow-state, low-carbon and ultra-high-performance concrete material, the concrete material has excellent mechanical properties and large flowability by utilizing the synergistic effect of the cementing material, the aggregate and the multi-stage steel fibers, the slump expansion degree can reach 500 mm or above, and the slump expansion degree can reach 500 mm or above. And the compressive strength reaches 160 MPa or above after 90 days of normal-temperature maintenance. The concrete material realizes reduction of carbon emission in the whole cycle from raw materials, production to construction, and has the advantages of high mechanical strength, high toughness, low cost, simple preparation, environmental friendliness and the like.
本发明公开了一种锰渣基超高性能复合胶凝材料及混凝土材料，该胶凝材料包括水泥、电解锰渣、硅灰、石灰石粉和硫酸钙晶须。该胶凝材料采用电解锰渣等固废材料取代部分水泥，极大地降低了水泥含量。该胶凝材料配合骨料、多级钢纤维和外加剂可制备大流态、低碳、超高性能的混凝土材料，利用胶凝材料与骨料和多级钢纤维的协同作用，使得混凝土材料具有优异的力学性能和大流动性，坍落扩展度可以达到500mm以上，常温养护下90d抗压强度达160MPa以上。该混凝土材料实现从原料、生产到施工实现了全周期碳排放的降低，具有力学强度高、韧性高、成本低廉、制备简单和对环境友好等优点。
