Description
Summary:In this paper, the applications of an electrical resistance method for monitoring of the state of steel reinforcement in concrete and its rate have been described. The following possibilities of the method were shown: an estimation of quantitative data on corroding steel reinforcement, including the values of a cross-sectional decrease, the depth of the corroded layer, the mass loss of steel material due to corrosion; the possibility of the mathematical modelling of the dependence of the rate of steel reinforcement on important factors like ambient relative humidity, concentration of chloride in embedding concrete and others; and obtaining quantitative data on corroding steel reinforcement by means of a potentiodynamic method through the results of the electrical resistance method and the related mathematical relationship.
