Abstract

Experiments on reinforced cylindrical concrete elements were carried out studying the influence of specimen size on corrosion of steel reinforcing bars and the extent of cracking of concrete. This work was achieved by accelerated corrosion of reinforced concrete cylinders subject to constant current conditions. Two concrete cylinder and reinforcing bar sizes were used. The effect of cracking on the specimen impedance and corrosion rate was evaluated and a correlation between time to concrete cover cracking and implications on service life was extrapolated. A cracking model as function of time and dimensions of the specimens was developed.
