低温施工水下不分散混凝土和自密实混凝土配制技术研究

Construction Technology of Underwater Non-dispersible & Self-compacting Concrete at Low Temperatures

本专题试验研究了冬期低温施工水下混凝土配制技术,通过掺入高效防冻剂技术,拓展了水下混凝土施工技术,使水下混凝土技术成为“全天候”施工技术,必将提高冬期低温施工水下混凝土的质量。

This paper describes the technology for preparation of underwater concrete used at low temperatures. By using anti-freezing agents, the construction technology for underwater concrete is broadened, thus making the underwater concreting technology an 'all-weather'one, which will undoubtedly improve the construction quality of underwater concrete at low temperatures in winters.
