Dataset Content: This dataset contains technical data for construction quality assurance and surface protective material assurance of port engineering concrete structures, including original test data of concrete mechanical properties, durability, and performance indicators of surface protective materials under different curing conditions, photos of test processes and equipment, analysis charts, test reports, review reports, 1 academic paper, and 1 group standard.
Data Source: Based on different set curing temperatures and curing ages, concrete compressive strength, chloride ion diffusion coefficient, as well as bond strength and immersion depth of concrete protected by surface coatings, silane and other protective materials were tested in accordance with the Standard for Durability Design of Water Transport Engineering Structures (JTS 153-2015). A prediction model for the performance of surface-protected concrete and equivalent age was established based on the maturity theory to determine the optimal coating age of surface protective materials. The group standard covers parameters of pouring and curing process for cast-in-place concrete structures in port engineering, performance requirements of concrete structures based on the functional gradient concept, methods for determining the anti-corrosion coating age of concrete under different structural types and environmental conditions, etc.
