Summary:The corrosion rate of carbon steel buried in a soil environment with changing water content was investigated. The soil used in this study was reddish gardening soil. AC impedance measurements were carried out at constant time interval in order to evaluate the corrosion rate of the carbon steel with changing water content in the soil. It was found that there is no proportional relationship between the corrosion rate and soil water content. The corrosion rate has the maximum value at a certain water content, which is determined by the balance between the water liquid and oxygen gas phases in soil.
