Abstract

This paper deals with the design and development of a PIC micro-controller based Muhichannel corrosion surveyor for RCC structures. Electrical potential between the remforcing steel and a reference electrode is named as half-cell. Based on the half-cell potential values, one can identify the area that is affected by corrosion. The developed system measures the half-cell potential at 4 locations and temperature at a single point simultaneously. This system has been developed according to the ASTM C876-80 standard, the basis of which is that the corrosion potential of the rebar will shift in the negative direction if the surface changes from the passive to the active state.
