*(Received November 21, 2014 / Revised December 15, 2014 / Accepted December 18, 2014)Recent interest in the increased structural performance and durability evaluation of this concrete structure in a salt damage environment is increasing. The most secure and reliable method of accelerated corrosion test is a method to carry out the rebar corrosion monitoring can be exposed directly to the marine test site exposure. However, long-term exposure testinghas the disadvantage that a long period is necessary. So, a lot of research on RC of salt damage environment have beenpromoted as alternatives to replace this. However, accelerated corrosion test, in the short term only is appropriate and is but an accelera ted test method to evaluate the critical chlorine concentration, there is a difficult problem that you still get the answer. It is one o f the correlation problems accelerated test correspond to a certain period of exposure environment. Therefore, in this study, to cla rify thedifferences rebar corrosion beginning, through the actual corrosion accelerated test in corrosion time and laboratory test cham ber of the structure of the marine environment results in both environments, it is an object of correlation coefficient derived. : , , , Keywords : Long-term exposure test, Accelerated corrosion test, Correlation coefficient, Corrosion time* Corresponding author E-mail: parkss87@smu.ac.kr
