摘要
钢筋混凝土结构在海洋工程建设中扮演着至关重要的角色,然而在严酷的海洋环境下,其结构会因腐蚀而过早失效,给国民经济造成重大损失。海工混凝土结构钢筋锈蚀防护的研究主要集中在如何减缓氯离子向钢筋表面的渗透迁移速率以及如何"捕获"或"驱除"从外界环境迁移至混凝土中的腐蚀介质上。根据国内外研究现状,从优化混凝土组成结构和附加保护措施两方面详细介绍了海工混凝土中钢筋锈蚀防护的研究进展,对钢筋锈蚀防护研究的热门问题进行了重点分析,并提出了见解和观点。
Reinforced concrete structure plays an important role in the construction of ocean engineering.However, its structure will fail due to corrosion in the harsh marine environment which will cause great loss to the national economy.Studying on corrosion protection of steel corrosion is mainly focused on how to reduce the penetration rate of chloride ion to the steel surface in marine concrete structure and transfer from the external environment to the corrosion media in concretes.The research progress of protection of steel corrosion in marine concrete is introduced in detail from two aspects, optimizing the structure and components of concrete and additional protection methods. And the hot spots of research on corrosion protection of steel reinforcement were analyzed.
