Cracks that occur after hardening usually are the result of drying shrinkage (Fig. 3)thermal contractionor subgrade settlement. While dryinghardened concrete will shrink about 1.6 mm in 3 m (116 in. in 10 ft) of length. To accommodate this shrinkage and control the location of cracksjoints are placed at regular intervals.Plastic shrinkage cracks appear in the surface of fresh concrete soon after it is placed and while it is still plastic. These cracks appear mostly on horizontal surfaces. They are usually parallel to each other on the order of 1 to 3 feet apartrelatively shallowand generally do not intersect the perimeter of the slab.
