Abstract

Corrosion sensors were devised to develop a system whereby the depth of chloride permeation from concrete surfaces can be monitored in cover concrete of reinforced concrete structures. For making sensor which is similar to rebar author uses Screen printer machines, Ag paste and Fe powder. Appropriate portion of Ag and Fe is over 1:2. The resistance of sensors increased as the degree of corrosion increased. And according to cover depth author suggests sensor system which has a demanded cover depth. It was therefore confirmed that the corrosion sensor can monitor chloride permeation by change of resistance.
