在我国经济发展中,土木工程基础设施建设对国民经济发展起到重要作用,特别是混凝土结构物在基础建设中有举足轻重的作用,然而,由于对结构物的耐久性不够重视,许多结构物过早地出现病害,影响使用,后期维修成本加大。通过提高对混凝土结构物耐久性的认识,加强结构裂缝控制,找出腐蚀机理,采用正确预防措施,改善混凝土特性,延长结构物使用寿命。
In China’s economic development, the construction of civil engineering infrastructure plays an important role in the development of the national economy. Concrete structures in particular play an important role in infrastructure construction. However, due to the lack of emphasis on the durability of structures, many structures Early disease, affecting the use of post-maintenance costs increase. By increasing awareness of the durability of concrete structures, strengthening structural crack control, identifying corrosion mechanisms, adopting proper precautions, improving concrete properties, and extending the life of structures.
