防水粉煤灰混凝土配合比设计防水混凝土是通过调整混凝土配合比、掺外加剂和掺合材或使用特种水泥等方法提高自身的密实性、抗渗性、使其满足抗渗等级大于S6的不透水性混凝土。防水混凝土一般分为普通防水混凝土、外加剂防水混凝土和膨胀剂防水混凝土3种。防水混凝土的防水机理 Waterproof fly ash concrete mix design Waterproof concrete is through the adjustment of concrete mix, admixture and admixture or the use of special cement and other methods to improve their own density, impermeability, impermeability grade to meet the impervious than S6 Permeable concrete. Waterproof concrete is generally divided into ordinary waterproof concrete, admixture of waterproof concrete and expansive waterproof concrete 3 kinds. Waterproof concrete waterproof mechanism
