Occupational Safety and Health Association (OSHA) <br />1. CFR Title 29 Part 1926 - Safety and Health Regulations for Construction <br />1.3 DEFINITIONS: <br />A. Construction Joints: <br />1. When fresh concrete is placed against a hardened concrete surface, the joint <br />between the two pours is called a construction joint. If indicated on the drawings, <br />joints in water bearing members shall be provided with a Waterstop and/or sealant <br />groove of the shape indicated. The surface of the first pour may also be required <br />to receive a coating of bond breaker as indicated. <br />B. Contraction Joints: <br />1. Contraction joints are similar to construction joints except that the fresh concrete <br />shall not bond to the hardened surface of the earlier pour, which shall be coated <br />with a bond breaker. The slab reinforcement shall be stopped 4-1/2 inches from <br />the joint, which is provided with a sleeve-type dowel, to allow shrinkage of the <br />concrete of the later pour. Waterstop and/or sealant groove shall also be provided <br />when indicated. <br />C. Expansion Joints: <br />1. To allow the concrete to expand freely, a space is provided between the two pours, <br />and the joint shall be formed as indicated. The space is obtained by placing a filler <br />joint material against the earlier pour, to act as a form for the later pour. Unless <br />otherwise indicated, expansion joints in water bearing members shall be provided <br />with a center-bulb type Waterstop as indicated. <br />2. Pre-molded expansion joint material shall be installed with the edge at the <br />indicated distance below or back from finished concrete surface, and shall have a <br />slightly tapered, dressed, and oiled wood strip secured to or placed at the edge <br />thereof during concrete placement, which shall later be removed to form space for <br />sealing material.
