1. Deposit and consolidate concrete slabs in a continuous operation, within <br /> limits of construction joints, until the placing of a panel or section is <br /> completed. <br /> 2. Bring slab surfaces to the correct level with a straightedge, and then <br /> strike off. <br /> 3. Use bullfloats or darbies to smooth the surface, leaving the surface free <br /> from bumps and hollows. - <br /> 4. Do not sprinkle water on the plastic surface. <br /> 5. Do not disturb the slab surface prior to start of finishing operations. <br /> 3.07 CONSOLIDATION _ <br /> A. Consolidate each layer of concrete immediately after placing by use of internal <br /> concrete vibrators and supplemented by hand spading, rodding, or tamping. <br /> B. Do not vibrate forms or reinforcement. <br /> C. Do not use vibrators to transport concrete inside the forms. <br /> 3.08 JOINTS <br /> A. Construction Joints: <br /> 1. Unless shown otherwise, do not use horizontal construction joints. <br /> 2. If construction joints are found to be required, submit for the Engineer's <br /> approval of joint design and location prior to start of concrete placement. <br /> B. Expansion Joints: <br /> 1. Do not permit reinforcement or other embedded metal items that are _ <br /> being bonded with concrete (except dowels in floors bonded on only one <br /> side of the joints) to extend continuously through any expansion joint. <br /> 2. Fill expansion joints full depth with expansion joint material. <br /> 3.09 CONCRETE FINISHING _ <br /> A. Unless otherwise indicated, provide the following slab finishes at the indicated <br /> locations: <br /> 1. Scratch finish: apply to monolithic slab surfaces that are to receive <br /> concrete floor topping or mortar setting bed. <br /> 2. Float finish: apply to monolithic slab surfaces that are to receive trowel <br /> finish and other finishes specified hereinafter, and to slab surfaces which <br /> are to be covered with insulation. _ <br /> Division III-89 NEI Phase II Water and Sewer <br /> July 2007 CIP Nos. 7468, 7589, 7590 <br />
