EVALUATION OF CORROSION INHIBITING PROPERTY OF POLYMER-MODIFIED MORTARS . PROCEEDINGS OF 3RD INTERNATIOAL CONFERENCE ON DETERIORATION AND REPAIR OF REINFORCED CONCRETE IN THE ARABIAN GULF, BAHRAIN, OCTOBER 21-24 1989. VOLUME 1.

This paper describes research in which polymer modified mortars using 3 types of commercial polymer (styrene butadiene rubber, latex, ethylene vinyl acetate, and polyacrylic ester) were prepared with different polymer cement ratios (10 and 20%) and tested for corrosion inhibiting properties under accelerated corrosion conditions. Ordinary portland cement and Toyoura standard sand were used to mix the mortars. The cylindrical mortar specimens in which two reinforcing steel bars were embedded were molded, and subjected to a combined water and dry cure. The corrosion-inhibiting property of the cured polymer-modified mortars exposed under severe corrosive conditions of carbonation and chloride penetration by pressurizing methods was examined, and the relationships between the polymer-cement ratio, the effects of test methods and the corrosion inhibition rate of the polymer-modified mortars were discussed. In conclusion, the corrosion-inhibiting property of the polymer-modified mortars was found to be superior, depending on the polymer type and polymer-cement ratio.(A) For the covering abstract of the conference see IRRD 828897.
