MEASURING THE RATE OF CORROSION OF REINFORCING STEEL IN CONCRETE

The progress on a research program directed at developing a nondestructive method for measuring the corrosion of steel in concrete as related to bridge deck deterioration is reported. Several polarization techniques for measuring the corrosion rate of steel in concrete are correlated to actual weight loss measured gravimetrically. The design of a prototype automated minicomputer system for measuring the corrosion of steel in concrete is also described. Included are the results of a laboratory basic study on the effect of pH, Cl-, O sub 2, and moisture on initiating and maintaining corrosion in mortar.
