浇筑水库大坝面板时，只要在混凝土中加入一种价钱不高的纤维材料，大坝表面就再也不会因产生裂缝而使坝体渗漏了。这项名为聚丙烯纤维混凝土的新技术，目前已开始在三峡工程中推广使用。聚丙烯纤维混凝土技术成功地攻克了水利工程施工中高标号水泥的防裂难题，具有防止或减少 When pouring the dam panel, as long as a low-cost fiber material is added into the concrete, the dam surface will no longer leak due to cracks. The new technology called polypropylene fiber concrete, has now started to promote the use of the Three Gorges Project. Polypropylene fiber concrete technology successfully overcome the hydraulic construction of high-grade cement cracking problems, with the prevention or reduction
