CORROSION BEHAVIOUR OF MILD STEEL IN SIMULATED CONCRETE PORE SOLUTION PREPARED IN RAIN WATER, WELL WATER AND SEA WATER

M Pandiarajan, P. Prabhakar, S Rajendran

Abstract


Concrete admixtures can be prepared in various water samples such as rain water, well water, and sea water. These waters contain various types of ions. So corrosion behaviour of mild steel immersed in simulated concrete pore solution prepared with the above water samples will vary. Corrosion resistance of mild steel in simulated concrete pore solution prepared with above water samples has been evaluated by polarization study. The corrosion resistance of mild steel in various samples of water is as follows: Rain water>Well water>Sea water. The corrosion resistance of mild steel in simulated concrete pore solution prepared in various water samples are in the decreasing order: Rain water>Well water> Sea water. This is revealed by the linear polarization resistance values and corrosion current values.
