干混抗冻混凝土配合比设计及抗冻性能研究

Dry-mixed antifreeze concretes design of mixing proportion and performance of winter

随着建筑市场的飞速发展,混凝土冬季施工在所难免。且我国北方地区气候寒冷,普通商品混凝土不能满足建筑工程要求。介绍一种特殊的混凝土——干混抗冻混凝土,通过模拟冬季施工环境,调整混凝土配合比,在满足混凝土强度要求前提下,找出最适宜的干混抗冻混凝土配合比。

With the rapid development of the construction market,concrete construction in winter is inevitable.Since the weather is cold,ordinary concrete construction can not meet the requirements.This paper describes a special concrete-dry-mixed concrete antifreeze. By simulating winter construction environment,adjust the concrete mix,concrete strength to meet the requirements of the premise,we want to identify the most suitable dry-mixed antifreeze concrete mix.
