由于水工大体积混凝土自身的特殊性、传统的设计模式及其所处的特殊环境 ,已经显示出其耐久性严重不足 ,主要表现为渗漏、溶蚀、侵蚀、冻融破坏和钢筋锈蚀 .而高性能混凝土自身的特点及其在许多水电工程中的成功应用 ,已经证明实现水工大体积混凝土高性能化是解决其耐久性问题的基本途径 .但是 ,目前尚需要解决高性能混凝土的造价问题和混凝土的新旧设计方法、设计观念之间的矛盾问题 ,这些问题可以通过更新设计观念、优选材料、优化配合比、采用新的施工工艺和进一步提高高性能混凝土的技术水平等措施来解决 .
Owing to the particularity of hydraulic concrete itself, the traditional design pattern and the special environment in which it is used have shown its serious lack of durability, mainly as leakage, erosion, erosion, freeze-thaw damage and steel corrosion. The characteristics of performance concrete and its successful application in many hydropower projects have proved that the realization of high performance hydraulic concrete mass is the basic way to solve the problem of durability.However, there is still need to solve the cost of high performance concrete and concrete The old and new design methods and design concepts, these problems can be solved by updating the design concept, optimizing materials, optimizing the mix, adopting new construction technology and further improving the technical level of high performance concrete.
