Rubber Gaskets for Circular Concrete Sewer Pipe and Culvert Pipe: ASTM C 443. 6.0 EXECUTION 6.1 FABRICATION AND PLACEMENT Perform fabrication in accordance with NPCA QC Manual and/orACPA QPC unless specified otherwise. 6.1.1 Forms Use forms, for manufacturing precast concrete products, of the type and design consistent with industry standards and practices. They should be capable of consistently providing uniform products and dimensions. Construct forms so that the forces and vibrations to which the forms will be subjected can cause no product damage. Clean forms of concrete build-up after each use. Apply form release agents according to the manufacturer's recommendations and do not allow to build up on the form casting surfaces. 6.1.2 Reinforcement Follow applicable ASTM Standard or ACI 318/318R for placement and splicing. Fabricate cages of reinforcement either by tying the bars, wires or welded wire fabric into rigid assemblies or by welding, where permissible, in accordance with AWS D1.4/D1.4M. Position reinforcing as specified by the design and so that the concrete cover conforms to requirements. The tolerance on concrete cover shall be one-third of that specified but not more than 1/2 inch. Provide concrete cover not less than 1/2 inch. Take positive means to assure that the reinforcement does not move significantly during the casting operations. 6.1.3 Embedded Items Position embedded items at locations specified in the design documents. Perform welding in accordance with AWS D1.1/D1.1M when necessary. Hold rigidly in place inserts, plates, weldments, lifting devices and other items to be imbedded in precast concrete products so that they do not move significantly during casting operations. 6..2 CONCRETE 6.2.1 Concrete Mixing Mixing operations shall produce batch-to-batch uniformity of strength, consistency, and appearance. 6.2.2 Concrete Placing Deposit concrete into forms as near to its final location as practical. Keep the free fall of the concrete to a minimum. Consolidate concrete in such a manner that segregation of the concrete is minimized and honeycombed areas are kept to a minimum. Use vibrators to consolidate concrete with frequencies and amplitudes sufficient to produce well consolidated concrete. 6.2.2.1 Cold Weather Concreting Perform cold weather concreting in accordance with ACI 306.1. a. Provide adequate equipment for heating concrete materials and protecting concrete during freezing or near-freezing weather. b. Free from frost all concrete materials and all reinforcement, forms, fillers, and ground with which concrete is to come in contact. c. Do not use frozen materials or materials containing ice. d. In cold weather the temperature of concrete at the time of placing shall not be below 45 degrees F. Discard concrete that freezes before its compressive strength reaches 500 psi. 6.2.2.2 Hot Weather Concreting Recommendations for hot weather concreting are given in detail in ACI 305R. During hot weather, give proper attention to constituents, production methods, handling, placing, protection, and curing to prevent excessive concrete temperatures or water evaporation that could impair required strength or serviceability of the member or structure. The temperatureof concrete at the time of placing shall not exceed 90 degrees F. 6.2.3 Concrete Curing Commence curing immediately following the initial set and completion of surface finishing. 6.2.3.1 Curing by Moisture Retention Preventmoisture evaporation from exposed surfaces until adequate strength for stripping is reached by one of the following methods: a. Cover with polyethylene sheets a minimum of 6 mils thick per ASTM C 171. b. Cover with burlap or other absorptive material and keep continually moist. c. Use of a membrane-curing compound applied at a rate not to exceed 200 square ft/gallon, or per manufacturers' recommendations according to ASTM C 309. 6.2.3.2 Curing with Heat and Moisture Do not subject concrete to steam or hot air until after the concrete has attained its initial set. Apply steam, if used, within a suitable enclosure, which permits free circulation of the steam in accordance with CAN/CSA A23.4. If hot air is used for curing, take precautions to prevent moisture loss from the concrete. The temperature of the concrete shall not be permitted to exceed 150 degrees F. These requirements do not apply to products cured with steam under pressure in an autoclave. 6.2.4 Surface Finish Finish unformed surfaces of wet-cast precast concrete products as specified. If no finishing procedure is specified, finish such surfaces using a strike-off to level the concrete with the top of the form. 6.2.4.1 Formed Non-Architectural Surfaces Cast surfaces against approved forms following industry practices in cleaning forms, designing concrete mixes, placing and curing concrete. Normal color variations, form joint marks, small surface holes caused by air bubbles, and minor chips and spalls will be accepted but no major imperfections, honeycombs or other major defects will be permitted. 6.2.5 Stripping Products from Forms Do not remove products from the forms until the concrete reaches the compressive strength for stripping required by the design. If no such requirement exists, products may be removed from the forms after the final set of concrete provided that stripping damage is minimal. 6.2.6 Patching and Repair No repair is required to formed surfaces that are relatively free of air voids and honeycombed areas, unless the surfaces are required by the design to be finished. 6.2.6.1 Repairing Minor Defects Defects that will not impair the functional use or expected life of a precast concrete product may be repaired by any method that does not impair the product. 6.2.6.2 Repairing Honeycombed Areas When honeycombed areas are to be repaired, remove all loose material and cut back the areas into essentially horizontal or vertical planes to a depth at which coarse aggregate particles break under chipping rather than being dislodged. Use proprietary repair materials in accordance with the manufacturer's instructions. If a proprietary repair material is not used, saturate the area with water. Immediately prior to repair, the area should be damp, but free of excess water. Apply a cement-sand grout or an approved bonding agent to the chipped surfaces, followed immediately by consolidating an appropriate repair material into the cavity. 6.2.6.3 Repairing Major Defects Evaluate, by qualified personnel, defects in precast concrete products which impairthe functional use or the expected life of products to determine if repairs are feasible and, if so, to establish the repair procedure. 6.2.7 Shipping Products Do not ship products until they are at least 5 days old, unless it can be shownthat the concrete strength has reached at least 75% of the specified 28-day strength, or that damage will not result, impairing the performance of the product.
