摘要
混凝土因抗压性强、价格低廉、资源丰富等优点而成为现代建筑最主要的结构材料,然而,因腐蚀诱发的耐久性问题成为限制其应用和发展的瓶颈。从物理、化学、生物3个因素深入分析了混凝土的腐蚀机理;全面地总结了无机类、有机类、以及无机-有机复合型等典型混凝土涂层的应用现状及其优缺点;介绍了自修复涂层、自清洁涂层等新型涂层的研究进展;最后探讨了混凝土涂层未来的发展趋势,以期对混凝土防护涂层的开发提供新思路。
Concrete has become the most important structural material for modern buildings due to its high compressive strength,low price cost and abundant resources.However,the durability problem induced by corrosion has been a bottleneck to limit its applications and development.In this work,an in-depth analysis of the corrosion mechanism of concrete was conducted from physical,chemical and biological factors.The application status,advantages and disadvantages of organic,inorganic and organic-inorganic composite typical concrete coatings were comprehensively summarized,the research progress of new coatings such as self-healing coatings and self-cleaning coatings was introduced.Finally,the future development trends of concrete coatings were discussed.This paper would provide new ideas for the development of concrete protective coatings.
