R•1,PRODUCNT EXPENSEED AT GOVERNME PART 3 - EXECUTION 3.1 FORMS: ACI 301. Set forms true to line and grade and make mortar - tight. Chamfer above grade exposed joints, edges, and external corners Of concrete 3/4 inch, unless otherwise indicated. Before concrete placement, coat the contact surfaces of forms with a nonstaining form coating compound. Do not use mineral oil on formed surfaces to be painted. Prevent concrete damage during form removal. 3.2 PLACING REINFORCEMENT AND MISCELLANEOUS MATERIALS: ACI 301. Provide bars, wire fabric, and other reinforcing materials, including wire ties, supports, and other devices necessary to install and secure the reinforcement. 3.2.1 Cover and Splicing: ACI 301, unless otherwise indicated. 3.2.2 Setting Miscellaneous Material: Place and secure anchors and bolts, pipe sleeves, conduits and other such items in position before concrete placement. Plumb anchor bolts and check location and elevation. Temporarily fill voids in sleeves with readily removable material to prevent the entry of concrete. 3.2.3 Construction Joints: ACI 301. Continue reinforcement across joints, unless otherwise indicated. 3.2.4 Expansion Joints and Contraction Joints: ACI 301. For slabs on grade, provide at edges of interior floor slabs, adjacent to walls, and as indicated. Make expansion joints 0.5 inch wide, except as indicated otherwise. Fill expansion joints not exposed to weather with preformed joint material. Seal joints exposed to weather with joint sealant. Do not extend reinforcement or other embedded metal items bonded to the concrete through any expansion joint, unless an expansion sleeve is used. Provide contraction joints, either formed or saw cut or cut with a jointing tool to the indicated depth after the surface has been finished. Sawed joints shall be completed within 4 to 12 hours after concrete placement. Protect joints from intrusion of foreign matter. 3.3 MEASURING, MIXING, TRANSPORTING, AND PLACING CONCRETE: ACI 304, except as modified herein. ASTM C 94; machine mix concrete and provide mandatory batch ticket information for each load of ready mix concrete. Begin mixing within 30 minutes after the cement has been added to the aggregates. Additional water may be added, provided that both the specified maximum slump and water -cement ratio are not exceeded. If the entrained air content falls below the specified limit, add a sufficient quantity of admixture to bring the entrained air content within the specified limits. Do not place concrete when weather conditions prevent proper placement and consolidation; in uncovered areas during periods of precipitation; or in standing water. Prior to placing concrete, remove dirt, construction debris, and water. Consolidate concrete slabs 4 inches or less in depth by tamping, spading, and settling with a heavy leveling straight edge. 12-88-3458 03302-5
