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