  • Abstract

    Concrete admixtures can be prepared in various water samples such as rainwater, well water, and seawater. These waters contain various types of ions. So corrosion behavior 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 AC impedance spectra. The corrosion resistance of mild steel in various samples of water is as follows: Rainwater>Well water>Seawater. The corrosion resistance of mild steel in simulated concrete pore solution prepared in various water samples are in the decreasing order: Rainwater > Well water > Seawater. This is revealed by charge transfer resistance values and double layer capacitance values.
