| Shrinkage cracks occur when the concrete slab dries out and shrinks slightly. Cracking is normal, and concrete typically shrinks about 1/16 in. simply a reduction in the volume of concrete as it hardens. If this reduction shrinkage and thus cracks occur.They do this by installing control joints and expansion or isolation joints. The recommended spacing of these joints, should be no further apart than twice the thickness of the slab in feet. The depth of the joints should be a minimum of 1/3 the thickness of the have a maximum spacing of 8 feet, a 6 inch thick slab would be 12 feet. The National Ready Mixed Concrete Association recognizes that cracks in concrete cannot be prevented entirely, but they can be controlled and minimized by properly designed joints and proper placement and curing practices. |
