The most common complaint for slabs-on-ground is random or out-of-joint cracking. Hear about the American Concrete Institute’s recommendations for controlling the location and widths of thermal/drying-shrinkage cracks in both unreinforced and reinforced slabs. Learn how to design both jointed and reinforced slabs or a combination of joints and reinforcing to control random slab cracking.
Learning Objectives:
-
Apply a crack control approach to minimize random cracking in slabs-on-ground
-
Layout a proper contraction joint layout and other requirements for unreinforced and reinforced slabs
-
How to use reinforcement to limit crack widths in slabs-on-ground (and slabs on metal decks)
-
Recognize potential problems associated with crack control schemes that combine both joints and reinforcing
