SYNOPSIS

The talk focuses on careless application of anodic or cathodic protection can cause the passivation breakdown of reinforcing steel in concrete.
Affecting factors on the mechanical properties of steel. Cement hydrates provide high pH condition for passivation. Point defect model depicts the development of passive film until corrosion. The phenomena observed during anodic potential polarization, pitting potential, corrosion products and breakdown mechanism. Hydrogen absorption during cathodic potential polarization induced fracture mechanism.
