Abstract
The relationships between the pore solution composition and the corrosion intensity evaluated by electrochemical measurements for the steel electrode embedded in mortars containing a reactive aggregate and chloride are experimentally discussed in order to reveal influences of the alkali-silica reaction on the corrosion of steel reinforcement in mortars. The alkali-silica reaction promotes the chloride-induced corrosion of steel bars embedded in mortars containing a reactive aggregate and a chloride. The extent of the promotion varies with the type of chloride. The relationships between the corrosion intensity and Cl-/OH- ratio in the pore solution in CaCl2-bearing mortars are very different from those in NaCl-bearing mortars.
