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 (LAB) and linear alkylbenzene sulfonate (LAS),   potentiokinetic experiments were carried out. Thus, by embedding steel   electrodes into concrete specimens with a water/cement (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.
