Description

Reinforced concrete is used to build many modern structures such as bridges and buildings. The strength of these structures is dependent upon the integrity of the steel reinforcing embedded in the concrete. Over a period of time the rebars may begin to corrode and crack. The loss of steel due to corrosion or the loss of strength due to cracking may lead to structural failure particularly for prestressed concrete. The work described in this paper is the development of active electromagnetic induction sensors capable of detecting reinforcing bars within concrete and the identification of surface breaking defects on the reinforcing bars.
