摘要
以水泥混凝土试件单位面积剥落量作为评价指标,在水泥混凝土拌合过程中降低水灰比,改善其内部的孔隙率和孔结构分布,增强抗渗密实度,达到提高水泥混凝土抗盐冻剥蚀性能的目的。实验结果表明,在满足水泥混凝土工作性的前提下,水泥混凝土水灰比越低,其抗盐冻剥蚀性能越强。
Combined with the cement concrete specimen flaking volume per unit area as the evaluation index, this paper reduced the water-cement ratio, improved its internal porosity and pore structure distribution,enhanced the impermeability compactness in the process of cement concrete mixing, which could improve the cement concrete salt resistance frozen erosion performance. The experimental results showed that the cement concrete water-cement ratio was lower, its salt resistance frozen erosion was stronger on the premise of satisfying the cement concrete workability.
