Propagation of the corrosion layer and model of corrosion distribution on steel re-enforcing bar in concrete
Abstract：The corrosion of concrete reinforcing bars in concrete was studied by corrosion tes- ting in artificial and natural conditions. Before the onset of corrosion cracking under natural cli- matic conditions corrosion is mainly distributed on the bar side facing the concrete cover. Maxi-mum corrosion is noted on the point nearest the concrete cover and corrosion is less on way from the concrete cover. The corrosion is distributed as a half ellipse around the the maximum toward the cover. Re-bar corrosion in the artificial climatic tests shows pattern. However, re-bar corrosion induced by the galvanostatic method is seen to be points a bar with a similar differentfrom that observed under natural climatic conditions.
