钢筋锈蚀导致的耐久性不足是混凝土结构劣化破坏的主要因素之一,其中由于氯盐侵蚀导致混凝土中钢筋锈蚀问题普遍存在且日趋严重。非常有必要对该破坏机理分析并提出有效对策,这对于提高混凝土结构耐久性寿命至关重要。 The lack of durability caused by corrosion of steel bars is one of the main factors that cause deterioration of concrete structure. Among them, corrosion of steel bars in concrete due to chloride corrosion is widespread and worsens. It is very necessary to analyze the failure mechanism and put forward effective countermeasures, which is very important to improve the durability life of concrete structure.
