EFFECT OF ZINC OXIDE ADMIXTURE ON CORROSION INHIBITION OF FERROCEMENT . ADMIXTURES FOR CONCRETE: IMPROVEMENT OF PROPERTIES. PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM HELD BY RILEM (THE INTERNATIONAL UNION OF TESTING AND RESEARCH LABORATORIES FOR MATERIALS AND STRUCTURES), BARCELONA, MAY 14-17, 1990

Ungalvanized wire mesh were embedded in cement mortars mixed with sweet water, sea water and 3% solution of calcium chloride, respectively. Corrosion state was monitored by the corrosion potential, and degree of the wire mesh corrosion was observed visually. Another electrochemical method was used; the anodic polarization curves of iron plate embedded in cement mortars were measured by the potentio-dynamic method. When the zinc oxide was added to the ferrocement in small amounts, the corrosion potential moved to noble or ignoble value and the current density increased, and the corrosion of wire mesh was inhibited. Zinc oxide as an admixture was very effective for inhibition of ferrocement corrosion. (Author/TRRL)
