ABSTRACT:
A stress reducing device for reducing or eliminating stress cracks in concrete slabs caused by shrinkage stresses at re-entrant corners of the concrete slab and method of use is provided. The stress reducing device is provided with a body member having a first and second leg, each leg having a first and second surface, the first surface of each leg defining an angle in the body member substantially corresponding to the angle of the re-entrant corner in a stem wall and the second surface of the first and second legs cooperating to define an arcuate concrete engaging surface for reducing concentration of stresses in the concrete slab adjacent the re-entrant corner.
