Impermeable concrete composition
The invention discloses an impervious concrete composition, and relates to the technical field of building materials, and the concrete composition is characterized by comprising cement, sand, stone, water, an additive and a mixed material, the mixed material is fly ash and mineral powder, and the additive is a polycarboxylic acid superplasticizer. The optimal value of the water-binder ratio of the concrete composition is 0.28. Preferably, the weight ratio of the cement to the sand to the stone to the water to the additive to the mixed material in the concrete composition is 1: 1.80: 2.55: 0.38: 0.038: 0.35. The concrete composition is simple in preparation method and high in impermeability.
本发明公开了一种抗渗的混凝土组合物，涉及建筑材料技术领域，其技术方案要点是：所述混凝土组合物包括水泥、砂、石、水、外加剂和混合材料，所述混合材料为粉煤灰和矿粉，所述外加剂为聚羧酸高效减水剂。所述混凝土组合物的水胶比最优值为0.28。所述混凝土组合物中各组分的重量比优选为：水泥：砂：石：水：外加剂：混合材料＝1：1.80：2.55：0.38：0.038：0.35。该混凝土组合物的制备方法简单、抗渗能力强。
