DETERMINATION OF CHLORIDE DIFFUSION COEFFICIENT OF HIGH-PERFORMANCE CONCRETE BY ELECTRICAL POTENTIAL TECHNIQUE

Electrical potential technique was used as an accelerated testing method to determine the chloride diffusion coefficient of high performance concrete. An electrical potential difference of 15 volts was applied to a disc-shaped concrete specimen of 50 mm in thickness. This direct current voltage increased the flux of chloride ions migrating through the concrete and permitted the determination of the chloride diffusion coefficient (D cl) within 3 to 4 weeks of the testing period.
