Abstract

The purpose of the this study of to define the critical corrosion amount of the steel cause the cracking of concrete cover. The major variables of the critical corrosion amount are concrete strength and thick of the concrete cover. In this experiment, the constant of stress concentration is added by a new variable. As a result of the experiment, it is confirmed to less decrease in the critical corrosion amount following the constants of stress concentration increased. Besides, electric currents were measured through a generator of constant voltage. When connecting constant voltage with corrosion circuit, it was discovered that magnitude of the change come out similarly between displacement on the concrete cover and electric current according to time.
