在冶金工业基本建设工程中,以及当前从深挖洞的需要而建筑的人防工程中,有大量的防水工程。不少地区的广大群众遵照“百年大计,质量第一”的精神,因地制宜,就地取材,采用了各种不同的防水材料,为搞好防水工程积累了丰富经验。我们根据几年来冶金工业建设中防水混凝土的使用情况,从本期起陆续介绍几种行之有效的防水混凝土,供参考。
In the basic construction projects of the metallurgical industry, and in the current civil air defense projects that require the construction of deep tunnels, there are a large number of waterproofing projects. Many people in many areas followed the “hundred-year plan, quality first” spirit, adapting to local conditions, drawing materials locally, and adopting a variety of different waterproof materials, accumulating rich experience in doing a good job of waterproofing. Based on the use of waterproof concrete in the metallurgical industry construction for several years, we have introduced several effective waterproof concretes for reference from this issue.
