With the aim of analysing the behaviour of concrete with replacements of ground clay bricks waste (GCBW) under reinforcement corrosion by chlorides, reinforced concrete specimens with 80 x 80 x 80 mm were cast. The replacements were set at 0 %, 10 % and 30 % of cement weight and the water to cement ratio at 0.55. After a 7-day wet curing and in a laboratory environment until the 180th day, the specimens were subjected to wetting and drying cycles in a 1M sodium-chloride solution. After identification of depassivation of the reinforcement, total and free chloride profiles were obtained for each specimen. The results show that, although there is a slight decrease in compressive strength and in critical chloride content with GCBW addition to concrete, concretes with GCBW tend to show a reduction in mass transport ability, which can override the previous aspect and extend the initiation period of corrosion.
