钢筋保护层作为混凝士结构中的特殊部位,对保证结构的安全性、适用性和耐久性具有重要意义,特别是对于沿海及近海地区的混凝士结构,它能有效延缓氯离子等有害物质的侵入,防止钢筋过早锈蚀,从而延长结构的使用寿命。然而,从目前的施工现状看,较普遍地存在着保护层质量问题,因此从根本上解决保护层的控制问题,保证建筑物的安全和使用寿命,已成为工程施工迫切需要解决的问题。 As a special part in the structure of concrete, reinforced protective layer is of great importance to ensure the safety, suitability and durability of the structure, especially for the coagulation structure in coastal and offshore areas, which can effectively delay the harmful effects of chloride ions and the like Material intrusion, to prevent premature corrosion of steel, thus extending the service life of the structure. However, judging from the current status of construction, the quality of the protective layer is more common. Therefore, to fundamentally solve the control of the protective layer and ensure the safety and service life of the building has become an urgent problem to be solved in engineering construction.
