The paper reports on long time testing of reinforcement corrosion in high strength normal and total-lightweight concretes exposed to cycles consisting of 4 phases: chloride salt fog, drying, sulphate solution immersion, drying. Polarisation resistance monitoring performed for evaluating corrosion rates confirmed passive condition for all reinforcements embedded in normalweight concretes. The initiation of the corrosive attack was detected in all the reinforcements in total-lightweight concretes. Corrosion rates up to 400 μm/year were detected.

Abstract
The paper reports on long time testing of reinforcement corrosion in high strength normal and total-lightweight concretes exposed to cycles consisting of 4 phases: chloride salt fog, drying, sulphate solution immersion, drying. Polarisation resistance monitoring performed for evaluating corrosion rates confirmed passive condition for all reinforcements embedded in normalweight concretes. The initiation of the corrosive attack was detected in all the reinforcements in total-lightweight concretes. Corrosion rates up to 400 μm/year were detected.File allegato/i alla scheda:
