Abstract :In order to investigate the corrosion of reinforcing steel in concrete and the effects of chloride ions, oxygen diffusion and detergent additives of linear alkylbenzene insert ignore into journalissuearticles values(LAB); and linear alkylbenzene sulfonate insert ignore into journalissuearticles values(LAS);, potentiokinetic experiments were carried out. Thus, by embedding steel electrodes into concrete specimens with a water/cement insert ignore into journalissuearticles values(W/C); ratio of 0.45, current-potential curves were obtained and the compressive strength of the specimens was measured. The electrochemical approach can be used to identify the effect of chloride on steel corrosion in concrete. It was found that the diffusion of chloride and oxygen through concrete and the reduction of oxygen on the metal surface are important parameters controlling reinforcing steel corrosion.
