内容記述 | [Abstract] Reiriforced-concrete structures in the marine environment often deteriorate in the early stages of their service life. The main cause is corrosion of the reinforcing steel and the concrete, which may interact adversely with each other. The deterioration, which is influenced by various factors, such as the mix proportion of the concrete, the depth of cover and the environmental conditions, results from physiochemical processes, such as ion transportation and carbonation. Transport phenomena through the pores of concrete may occur by the penetration and diffusion of substances such as chloride ions, carbon dioxide and sulfate. The results of the pulse-velocity measurements over 5 years show that lining the concrete surface can inhibit its deterioration. The half-cell potential and polarization resistance test results show that the corrosion of reinforcing steel increases with exposure time. The results of potentiometric titration, X-ray diffraction and microanalysis show that chloride penetration and diffusion are influenced by the mix proportion and the casting direction of the concrete and the setting conditions at the marine site. This study is discussed about the results of the non-destructive measurements in exposure sites and the physiochemical measurements in laboratory, and discussed about the estimation of deterioration from those results. | |||||||||
