Evaluation of Corrosion-Inhibiting Concrete Admixtures
This report evaluates the use of corrosion-inhibiting admixtures for constructability, and workability when used along with epoxy coated rebar. Deicing agents contain chloride ions that corrode the steel reinforcement. An expoxy-coated rebar has been used since the 1970's however the epoxy coating controls the problem only to an extent. Corrosion of the steel reinforcements still occurs. As a result, the Department is interested in the performance of corrosion-inhibiting concrete admixtures. Two manufacturers, Sika Corporation and W.R. Grace Concrete Products, supplied corrosion-inhibiting concrete admixtures to be tested for their workability, constructability, placement, and performance. According to the contractor's personnel, and the Departments inspectors, there were no workability, constructability, or placement problems with the corrosion-inhibiting admixtures. Periodic checks have been made since construction, and the two test bridges appear to be performing well.
