For the attainment of least amount of rate of corrosion, different percentages of nano particle ZrO2 is added to epoxy to give a neat coating. The optimum dosage of ZrO2 is found out in order to control the rate of corrosion of rebar embedded in concrete. The composite coated, i.e, nanoZrO2 and epoxy coated specimens are placed in alkaline medium, namely 5% NaCl solution. The rate of corrosion readings were noted down using the reference electrode (calomel) and voltmeter. The rate of flow of current is proportional to rate of corrosion. The readings were noted down over a period of time; 0th day, 1st week, 2nd week, 3rd week and 4th week ; to have a clear idea about the extent of corrosion taking place in the alkaline medium. The optimum percentage of nanoZrO2 to be was found out to be 2%. The test also comprise of evaluating the bond strength between the rebar’s and concrete with that of control specimen.
Key words: Rebar Corrosion / Epoxy coating / Zirconium.
