P·I型硅酸盐水泥和大掺量复合矿物掺合料在预拌混凝土中的应用研究

Application of the Portland cement(P·I) and high volume composite mineral admixture in ready-mixed concrete

混凝土应用P·I水泥,掺加不同品种、不同比例的矿物掺合料,可提高混凝土的和易性,改善水泥与外加剂的适应性。使用改性的新型外加剂,可进一步提高矿物掺合料的掺加比例,提高混凝土后期强度,降低混凝土生产成本。

With utilizing P·I cement and adding different variety and proportion mineral admixture in the concrete, the concrete workability and cement and admixture adaptability improves.The new type of modification admixture can increase the proportion of mineral admixture in concrete more and improve the post-strength of concrete while reducing the production cost of concrete.
