CIP 6—Joints in Concrete Slabs on Grade
For example, the joint spacing for a 4-inch [100 mm] thick slab should be about 10 feet [3 m]. It is further recommended that joint spacing be limited to a maximum of 15 feet [4.5 m]. All panels

While control joints are neat and deliberate, cold joints are unintended, often uneven lines or planes in the concrete that don''t benefit from pre-planning. Control joints play a positive role in
