MEASUREMENT OF CONCRETE RESISTIVITY FOR ASSESSMENT OF CORROSION SEVERITY OF STEEL USING WENNER TECHNIQUE

The Wenner technique is becoming increasingly popular for measuring resistivity of reinforced concrete to assess the rate of corrosion of the steel reinforcement once it becomes depassivated by chloride attack or carbonation. This paper summarizes work carried out over several years in assessing the efficiency of this technique. Several sources of measurement error are identified, and recommendations are put forward to enable engineers to obtain more accurate results when using this technique in practical situations to evaluate the severity of ongoing corrosion problems.
