水利工程中水工碾压混凝土的耐久性直接关系到工程的使用寿命、加固费用、效益发挥和运行安全。由于工程耐久性不足,增加了使用过程中的修理与加固费用,影响或限制了结构的正常使用功能并缩短结构的使用年限,影响效益和安全,不仅造成经济损失,而且严重浪费资源,引发社会问题。 Hydraulic Engineering Hydraulic RCC durability is directly related to the life of the project, strengthening the cost, efficiency and operational safety. Due to the lack of durability of the project, the cost of repairing and strengthening the utility course is increased, the normal use function of the structure is affected or limited, the service life of the structure is shortened, the benefit and safety are affected, not only the economic loss but also the serious waste of resources and the social problem.
