An Electrochemical Investigation of Corrosion Rates for 1020 Steel in Environments Which Simulate Conditions in Marine Reinforced Concrete.

Abstract

An electrochemical investigation was conducted on the effects of varying the chloride and dissolved oxygen concentration on the corrosion rate of 1020 steel in a saturated calcium hydroxide solution. This solution was intended to simulate the conditions in marine reinforced concrete. The rate and mode of attack were studied electrochemically and microscopically. The electrochemical methods used were the Immersion Mass Loss (IML) Method, the Linear Polarization Method (LPM), the Potentiodynamic Polarization (PDP) Method, and the Potentiostatic Polarization (PSP) Method. The rates of corrosion obtained by each method were correlated to determine the corrosion rate of reinforcing steel in marine reinforced concrete. Microscopic examinations were made, using optical and scanning electron microscopy, to determine the mode of attack and the distribution of corrosion products. (Author)
