whereas others observed that the moisture in the concreteis entrapped ?Berver et al. 2001; Pantazopoulou et al. 2001?. Mostof these research studies accelerated the corrosion reaction usingthe impressed electric current between anode and cathode. On theother hand, Debaiky et al. ?2002? insisted that the acceleratedcorrosion process with the impressed electric current results inunnatural corrosion damage and thus used an aggressive environ-ment consisting of 3% saline solution and high temperatures.However, this procedure requires a longer time period for testing
