改革开放以来,我国建筑行业经历了发展的黄金时期,新材料、新技术被不断引用到生产实际中,在施工质量以及施工效率上都有了极大的提升,但相对于国外发达国家而言,我国在混凝土施工技术上的研究时间相关较短,在实际施工中还存在着这样那样的问题,特别是在混凝土冻融方面上仍有许多问题没有解决,这主要是由于我国幅员辽阔,多数地区地处严寒地带,混凝土路面经常要受到严寒环境侵蚀。本文作者结合自身多年的实践经验,详细介绍了盐冻破坏现场与实验室研究的研究成果,分析了混凝土冻融破坏的表现形式,并对控制因素、机理、防治措施和解决方面进行了仔细介绍,希望为我国混凝土建筑行业的发展提供一定的导向作用。
Since the reform and opening up, China’s construction industry has experienced a golden period of development. New materials and new technologies have been continuously quoted in the actual production, which have greatly improved the construction quality and construction efficiency. However, compared with the developed countries in the world , Our country in the concrete construction technology time is relatively short, in the actual construction there is still such a problem, especially in the concrete freeze-thaw area there are still many problems not solved, mainly due to our vast territory, the majority The area is located in a cold area where concrete pavements are often eroded by cold conditions. Based on many years of practical experience, the author introduces the research results of salt frost damage on site and laboratory research in detail, analyzes the manifestations of concrete freeze-thaw damage, and carefully introduces the control factors, mechanism, prevention measures and solutions , Hoping to provide some guidance for the development of China’s concrete construction industry.
