水下不分散混凝土的研究与应用开发

Research and Application Development of Non Dispersible Underwater Concrete

本文介绍了国内外水下不分散混凝土及其外加剂的研究进展、应用特色及目前的发展趋势。结合国外一些典型的工程实例 ,讨论了根据不同现场条件 (水深、作业面积等 )和工程要求 (造价、混凝土标号及流动性、浇灌方式及机具、凝结时间等 )所采取的水下不分散混凝土技术上的对策。

This article introduces the research progress,application feature and development tendency of non dispersible underwater concrete and its polymer admixtures.Combined with some typical application projects overseas,the paper discussed technological measures for non dispersible underwater concrete concerning different conditions,such as on site circumstances(water depth,areas of construction ete.)and qualities requirements(cost,comprehensive strength,fluidity,placing methods and tools as well as setting time etc.). 〔
