ABSTRACT:
A nondestructive detection apparatus for detecting tendon failures in a prestressed concrete slab. The detection apparatus includes a cart adapted to be moved over the prestressed concrete slab. A metal sensor and a distance meter are connected to the cart. As the cart is moved over the slab, the metal sensor takes readings of a length of tendon and the distance meter measures the distance traversed by the cart. The detection apparatus also includes a controller that interfaces with the metal sensor and the distance meter. The controller is constructed and arranged to sample the readings generated by the metal sensor at predetermined distance intervals traversed by the cart.
