Dataset Content: Based on the survey data of service environment and engineering durability of coastal port engineering structures in China, this study investigates the long-term performance degradation law of port engineering concrete and protective materials. A total of 120 corrosion-observed wharf berth datasets have been collected, and two databases have been developed, namely the Corrosion Database of Coastal Port Engineering Structures in China and the Corrosion Degree Prototype Database. The submitted data includes on-site survey photos, test process photos, original experimental record data, charts, on-site witness reports, 1 software copyright, and 2 published academic papers.
Data Source: Focusing on the evolution characteristics of long-term service performance of coastal port engineering structures in China, corrosion environment and engineering durability surveys were conducted on typical port structures in northern China, East China, South China and other regions. The following indicators were analyzed: the appearance degradation degree of wharf concrete structures with different service years, concrete rebound strength, thickness of reinforced concrete protective layer, chloride ion diffusion performance, carbonation performance, steel bar corrosion potential, as well as the wall thickness, corrosion potential and coating performance of steel structures. The law of concrete performance degradation of coastal port engineering structures and the long-term protective effect of surface protective materials such as surface coatings and silane impregnation were summarized and analyzed.
Collection Location and Time: On-site at coastal wharfs in typical regions of northern China, East China and South China, and the laboratory of CCCC Fourth Harbor Engineering Institute Co., Ltd.; from December 2022 to June 2025.
