Mineral powder-based steel slag compact concrete
The invention relates to the technical field of concrete, in particular to mineral powder-based steel slag compact concrete which at least comprises the following components in parts by weight: 0.7-2part of Portland cement, 10-13 parts of mineral powder; 10-16 parts of fine steel slag; 40-50 parts of crude steel slag; 0.4-0.8 part of anhydrite ground powder; 0.0555-0.316 part of s10 polycarboxylate superplasticizer; 5-8 parts of yellow sand; 10-16, a reclaimed material; and 4.44-7.9 parts of water, wherein the particle size of the fine steel slag is 0-0.8 mm, and the particle size of the yellow sand is 0.25 mm and 0.5 mm. The maximum cement replacing amount of the mineral powder can reach 94%, the using requirement is still met, and the cost can be saved.
本发明涉及混凝土技术领域，特别是涉及一种矿粉基钢渣密实砼，所述钢渣密实砼至少包括以下重量份的组分：硅酸盐水泥，0.7‑2；矿粉，10‑13；细钢渣，10‑16；粗钢渣，40‑50；硬石膏磨细粉，0.4‑0.8；S10聚羧酸减水剂，0.0555‑0.316；黄砂：5‑8；再生料，10‑16；水，4.44‑7.9，所述细钢渣的粒径为0‑0.8mm，所述黄砂的粒径为0.25mm‑0.5mm。本发明中的矿粉替代水泥量最高可达94％，且仍满足使用需求，可节约成本。
