Análise estrutural e patológica das torres de iluminação das praias de santos

The assault on the concrete for carbonatation and chloride ions in coastal areas can cause corrosion of the reinforcement, this phenomenon requires special attention because in marine environments, the atmosphere is impregnated saline mainly by chloride ions. These ions are absorbed by the pores of the structure and subsequently diffuse toward the concrete reinforcement. The corrosion rate of the reinforcement is accelerated in the case of carbonated concrete and subjected to salt atmosphere. The carbonated concrete reduces the critical level of chloride required for corrosion to occur, and when the armor is hit, the pole must be recovered or replaced. The predominant factor for carbonatation that there is the presence of carbon dioxide (CO2) in the air, since the mobility of the chloride ion structures in the sea, they
