Abstract :

► Pozzolanic addition means more total charge demanded for the treatment. ► Increasing concrete cover thickness will increase total charge for realkalisation. ► Lower water to cement ratio means more total charge demanded for the treatment. ► Reinforcement repassivation can be seen by corrosion potential measurements. ► More charge demanded for realkalisation means a shorter time for repassivation.
