Hydraulic concrete singly doped with limestone powder admixture
The invention relates to hydraulic concrete singly doped with a limestone powder admixture, and belongs to the technical field of hydraulic building concrete of water conservancy and hydropower engineering materials. The hydraulic concrete is prepared from the following materials in proportion: the water-binder ratio is 0.51-0.60, the sand ratio is 37%-41%, the mixing amount of limestone powder is 10%-30%, and the mixing amount of an HLPCA polycarboxylate high-performance water reducing agent is 1.10%. Each cubic meter of hydraulic concrete comprises the following materials: (I) cement, limestone powder, sand, small stones of 5-20 mm, medium stones of 20-40 mm and large stones of 40-80 mm; water; an HLPCA polycarboxylate high-performance water reducing agent; or (II) cement, limestone powder, sand, small stones of 5-20 mm and medium stones of 20-40 mm; water; the invention relates to an HLPCA polycarboxylate high-performance water reducing agent. The concrete has the advantages of improving the strength, impermeability and frost resistance of the concrete and reducing the overall production cost of the concrete.
本发明一种单掺石灰石粉掺和料的水工混凝土，属于水利水电工程材料水工建筑混凝土技术领域。所述水工混凝土由以下材料进行配比：水胶比0.51～0.60、砂率37％～41％、石灰石粉掺量10％～30％、HLPCA聚羧酸盐高性能减水剂掺量1.10％；每立方米水工混凝土中各材料分别为：(I)水泥、石灰石粉、砂、5～20mm小石、20～40mm中石、40～80mm大石；水；HLPCA聚羧酸盐高性能减水剂；或(II)水泥、石灰石粉、砂、5～20mm小石、20～40mm中石；水；HLPCA聚羧酸盐高性能减水剂。本发明具有提高混凝土的强度、抗渗性能和抗冻性能和降低混凝土整体生产成本的优点。
