对于混凝土工程来说,冬期混凝土的施工难度是较大的,关于混凝土的冬施过程中的工艺、方法及混凝土外加剂的使用和混凝土不同气候环境中强度的发展情况,在人们的生产实践中得到不断的提高和发展,对大自然带来的不利因素,有了防范的手段,从而加快了冬期施工速度。铁电工程地处新疆拜城县境内,长年最低气温可在-30℃,一九八六年、一九八七 For concrete works, the construction of winter concrete is more difficult. Regarding the process and method of concrete in winter, the use of concrete admixtures and the development of concrete in different climatic environments, in people’s production practices. It has been continuously improved and developed, and it has taken precautionary measures against the unfavorable factors brought by nature, thus accelerating the speed of winter construction. The ferroelectric project is located in Baicheng County, Xinjiang. The minimum temperature for many years is -30°C, 1986 and 1987.
