In this paper, a review is presented of various applications of the magnetostrictive sensor (MsS) technology to the nondestructive evaluation of steel reinforcing bars and seven-wire strands. MsSs have been applied to the detection of corrosion in and out of concrete, the quantification of corrosion, the detection of debonding, the measurement of tensile stress, the monitoring of concrete curing, the monitoring of wire breakage, and the location of broken or fractured wires. A review of the MsS technology is given along with an assessment of the utility of the technology in the above-mentioned applications.
