干混抗冻混凝土配合比设计及抗冻性能研究

摘要

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.
