Evaluation Research on Applicability of Rapid Iodide Migration Test宋子健1,JIANG Linhua1,2,CHU Hongqiang2,XIONG Chuansheng21. College of Civil and Transportation, Hohai University2. College of Mechanics and Materials, Hohai University摘 要:The applicability of the rapid iodide migration test was systematically studied. Comparative experimental tests......
in the process of electrolysis were analyzed. The results show that piezoelectric acceleration sensor not only meets the basic requirements of electrolytic method for reducing the test apparatus, but also meets the accuracy requirements of the large model wave velocity test. At the initial stage of electrolytic desaturation process, the decreasing amplitude of the compression wave velocity......
aluminium alloy in marine atmosphere was studied. Salt fog test was used to simulate the marine atmospheric environment. Electrochemical impedance spectroscopy (EIS) and scanning Kelvin probe (SKP) were... the beginning exposure period. Pittings appear in the initial stage of salt fog test and link each other to expand with prolonging test time. The electrochemical impedance magnitude declines during......

with different corrosion levels and stirrup ratios were verified with the corresponding test results. The results show that the skeleton curves of the established restoring force model are in good agreement with the test results. The model captures the hysteretic response of the corroded specimens under low reversed cyclic loads well. The research results is helpful for the nonlinear numerical......
