Abstract

The contribution of this work is the design of microcomputer based system
for measurement, monitoring and pulse width modulated power supply
(PWM) as integrated control system with strong software suitable for
different electrochemical control techniques of the reinforced concrete
corrosion and repair locations. The combination of sacrificial (galvanic)
and impressed current cathodic protection was laboratory tested with the
proposed control system. The corrosion tendencies as measured by
potential, are determined according to ASTM C876-87 half-cell method.
In this work, the study of reinforced concrete steel corrosion under
different conditions is presented. The behavior of Aluminum anode and its
stability as a reference electrode was studied.
