混凝土结构耐久性检测与加固技术

影响混凝土结构耐久性的因素是十分复杂的,不同影响因素对混凝土结构耐久性的影响也各不相同.主要基于材料、构件以及结构三个层面进行分析和研究,从外部环境影响考虑,主要有混凝土受空气二氧化碳的碳化侵蚀,进而引起钢筋锈蚀,寒冷地区的冻融循环和有害离子的侵蚀,内部因素主要有碱骨料反应.本文主要介绍了基于以上几种影响因素的检测手段...

Durability detection and reinforcement technology of concrete structure

The factors that affect the durability of concrete structures are very complex,and the influence of different influencing factors on the durability of concrete structures is also different.The study is mainly based on three levels of material,component and structure.From the external environmental influence,concrete is mainly carbonized by air carbon dioxide,which leads to steel corrosion,as well as freeze-thaw cycle and harmful ion erosion in cold areas,and the internal factors are mainly alkali aggregate reaction.This article mainly introduced based on the above several factors affecting the testing means and methods,for the durability of the concrete solution,should be based on the definition of concrete durability,the component and structure detection of regular maintenance,and to reinforce timely according to local damage,thus speeding up the development of the detection and reinforcement of concrete technology.
