Effects of Anti-Corrosion Coating/Treating Ages on  Performance Evolution of Marine Cast-in-Place Concrete

Abstract

Abstract: This article was based on indoor simulated marine environment erosion tests using concrete, by analyzing the compressive strength, coating bonding strength and chloride ion diffusion behavior of marine cast-in-place concrete after erosion, and the effects of anti-corrosion coating/treating ages on the mechanical properties and durability evolution of marine cast-in-place concrete were studied. The results show that compared with concrete without anti-corrosion coating/treating, anti-corrosion coating/treating concrete using silane and polyurethane coating shows a decrease in compressive strength f_c after erosion in marine tidal areas, and concrete f_c gradually decreases with the increase of curing age t_c. Anti-corrosion coating/treating can effectively improve the long-term chloride ion erosion resistance of marine cast-in-place concrete, and with the increase of curing age t_c, the effects of anti-corrosion coating/treating on reducing the surface chloride ion content C_s and apparent chloride ion diffusion coefficient D_a of concrete becomes more significant. Taking into account the development of mechanical properties of cast-in-place concrete in the marine tidal zone environment and the effectiveness of anti-corrosion coating/treating measures, it is recommended to use silane and polyurethane coatings for coating with a curing age of not less than 5 and 10 d, respectively.

Key words: marine cast-in-place concrete, anti-corrosion coating/treating, mechanical property, chloride diffusion, durability
