Abstract
In this study, to clarify the differences rebar corrosion beginning, through the actual corrosion accelerated test in corrosion time and laboratory test chamber of the structure of the marine environment results in both environments, it is an object of correlation coefficient derived. The accelerated corrosion test was carried out by two case, I.e., one is $20^{\circ}C$ of low temperaure codition(case 1), and the other is $65^{\circ}C$ of high temperaute codition(case 2). Whether corroions occurs, it was measures using half-cell potential method. The results indicated that case 2 is to acclerate the corrosion of rebar about 1.7~1.8 times as compared with case 1, thenthe corrosion of rebar embadded in concrete occurred according to the order of OPC60, FA, BS, OPC35. Correlation coefficient between acclerated corrosion test and long-term exposure test, case 1 is 2.45 to 2.94, and case 2 is 4.37~4.99.
