水工混凝土除强度和易性外,还要求耐久性,耐久性包括抗掺性、抗冻性、抗水性等特殊性能,而抗溶性最为重要,不仅直接影响水工建筑物的阻水性能,同时也是解决工程耐久的主要关键。以抵抗环境水的侵蚀来说,假如抗渗性高,混凝土组织密实,外界破坏因素不致侵入内部而造成危害;假如抗渗性差,不但坝面渗漏,同时由混凝土中溶解出 In addition to the strength and workability of hydraulic concrete, but also requires durability, durability, including anti-adulteration, frost resistance, water resistance and other special properties, and the most important anti-soluble, not only directly affect the hydraulic properties of hydraulic structures, It is also the key to solving the project’s durability. To resist the erosion of environmental water, if impermeability is high, the concrete structure is dense, the external damage factors will not invade the interior and cause harm; if impermeability is poor, not only the leakage of the dam surface, while dissolved from the concrete
