摘要
低温季节抢工，是水利工程施工经常遇到的重要技术问题之一。通过对掺防冻剂低温混凝土的效能及施工实用配合比进行了研究论证，结果表明，为确保工程质量，与常温季节施工相比，掺防冻剂低温混凝土，其胶凝材料用量以提高15％左右为宜。成果用于南水北调中线京石段2006年、2007年度冬期施工，收到较好效果。
Working in low temperature seasons is one of crucial technical issues in the water conservancy construction. This article makes a research and demonstration on the efficiency of the low temperature antifreezing concrete admixed with antifreeze and its practical mix proportion in construction, A better result is attained by using the research findings in 2006 2007 winter construction in Jingshi Section of the Middle Route of the South-to-North Water Transfer Project.
