乌鲁木齐地处寒冷地区,冬施期每年长达五个月,月平均气温-1.86～-13.7℃,最低平均气温-5.1～-18℃。在如此长而低温的环境中施工,如何选择一种简便可行的冬施方案,具有很大现实意义。近几年来,我们在学习黑龙江低温建研所负温混凝土的基础上,针对乌市具体情况,进行了连续试验和实践,取得了较好效果。 Urumqi is located in a cold area. The winter period is as long as five months each year. The average monthly temperature is -1.86 to -13.7°C and the minimum average temperature is -5.1 to -18°C. In such a long and low temperature environment, how to choose a simple and feasible winter program is of great practical significance. In recent years, on the basis of studying the negative temperature concrete of the Heilongjiang Institute of Low-temperature Research, we have conducted continuous experiments and practices against specific conditions in Urumchi and achieved good results.
