Concrete highly doped with mineral powder and preparation method thereof
The invention discloses concrete highly doped with mineral powder, and belongs to the technical field of concrete production. The concrete highly doped with mineral powder comprises the following components in parts by weight: 400-530 parts of a cementing material, 840-1000 parts of broken stone, 480-600 parts of river sand, 48-52 parts of an exciting agent, 52-62 parts of an expanding agent, 3-7 parts of a water reducing agent and 80-96 parts of water, wherein the cementing material is composed of ordinary Portland cement, slag powder and fly ash, the slag powder accounts for 42-63% of the total mass of the cementing material, and the fly ash accounts for 15-20% of the total mass of the cementing material. The slag powder and the fly ash are doped into the concrete, so that temperature difference cracks caused by cement hydration can be reduced, the integrity of a concrete structure is improved, and the durability of the concrete is improved; by utilizing industrial wastes such as mineral powder and fly ash, the cement consumption in the premixed concrete is reduced, the cost is reduced, and energy conservation and environmental protection are realized.
本发明公开了一种高掺矿粉混凝土，属于混凝土生产技术领域。所述一种高掺矿粉混凝土，包括以下重量份的组分：400～530份胶凝材料、840～1000份碎石、480～600份河砂、48～52份激发剂、52～62份膨胀剂、3～7份减水剂和80～96份水；其中，所述胶凝材料由普通硅酸盐水泥、矿渣粉和粉煤灰组成，所述矿渣粉占所述胶凝材料总质量的42～63％，所述粉煤灰质量为所述胶凝材料总质量的15～20％。矿渣粉和粉煤灰掺入混凝土，可减少因水泥水化而产生的温差裂缝，提高了混凝土结构的整体性，从而提高混凝土的耐久性；利用矿粉、粉煤灰等工业废弃物，减少预拌混凝土中水泥用量，降低成本，节能环保。
