Mason SW Rehab 03390-2 Concrete Curing May 2012 PART 3 EXECUTION 3.01 GENERAL Beginning immediately after placement, concrete shall be protected from premature drying, excessively hot or cold temperatures, and mechanical injury, and shall be maintained with minimal moisture loss at a relatively constant temperature for the period necessary for hydration of the cement and hardening of the concrete in accordance with ACI 308, "Standard Practice for Curing Concrete". The materials and method of curing shall be subject to review and acceptance by the ENGINEER. Specific curing requirements may be called out on the Drawings or other Technical Specifications. Curing shall be continued for at least seven days. Alternatively, if tests are made of cylinders kept adjacent to the structure and cured by the same methods, moisture retention measures may be terminated when the average compressive strength has reached 70% of the specified concrete strength. When a spray applied membrane -curing compound is used, it shall be applied in two coats with the second coat applied at right angles to the first coat. 3.02 EVAPORATIVE RETARDANT An evaporative retardant shall be used during concrete placement for water retaining structure floor and roof slabs and other slabs larger than 2,500 square feet in size. The retardant shall be sprayed using a power sprayer at a rate of 10 gallons per 2,000 square feet after screeding and repeated after the first floating operation. The evaporative retardant shall not be applied during the final steel troweling operations or after the water sheen has disappeared from the concrete surface. 3.03 SLABS For concrete surfaces not in contact with forms, a procedure determined by the ENGINEER shall be applied immediately after completion of placement and finishing. 3.04 WALLS AND COLUMNS Moisture loss from surfaces placed against wooden or metal forms exposed to heating by the sun shall be minimized by keeping the forms wet until they can be safely removed. After form removal, the concrete shall be cured until the end of the curing time by one of the previously described curing methods. Concrete shall not be placed against forms that have been exposed to air below freezing temperatures until the forms have been heated so that the surface temperature of the form is >_ 401 F. The top of walls and columns not covered by forms shall be cured using a membrane - curing compound conforming to ASTM C 309 immediately after placement 3.05 OTHER SURFACES Unless otherwise shown in the Drawings all other surfaces shall be cured using two applications of a membrane -curing compound conforming to ASTM C 309. The second application shall be applied at 900 to the first application. Mason SW Rehab 03390-3 Concrete Curing May 2012 3.06 COLD WEATHER Curing during cold weather conditions shall include the above methods except for water cure unless measures are taken to prevent freezing of the water. 3.07 HOT WEATHER If the rate of evaporation approaches 0.2 Ib/ft2/hr, as estimated by ACI 305, precautions against plastic shrinkage cracking are required. The CONTRACTOR shall have a recording thermometer, hygrometer and wind gage on site seven days prior to first concrete placement. When necessary, provision for windbreaks, shading, fog spraying, sprinkling, ponding, or wet covering with a light colored material shall be made in advance of placement, and such protective measures shall be taken as quickly as concrete hardening and finishing operations will allow. Precautions against plastic shrinkage cracks may be required in conditions other than what is normally considered hot weather conditions. 3.08 RATE OF TEMPERATURE CHANGE Changes in temperature of the air immediately adjacent to the concrete during and immediately following the curing period shall be kept as uniform as possible and shall not exceed 5° F in any one hour or 500 F in any 24-hour period. 3.09 PROTECTION FROM MECHANICAL INJURY During the curing period, the concrete shall be protected from damaging mechanical disturbances, such as load stresses, heavy shock, and excessive vibration.

The joint assemblies shall be accurately formed so that when each pipe section is forced together in the trench the assembled pipe shall form a continuous watertight conduit with smooth and uniform interior surface, and shall provide for slight movement of any piece of the pipeline due to expansion, contraction, settlement or lateral displacement. The gasket shall be the sole element of the joint providing water tightness. The ends of the pipe shall be in planes at right angles to the longitudinal centerline of the pipe, except where bevel -end pipe is required. The ends shall be furnished to regular smooth surfaces. All joints and jointing material shall conform to the following minimum requirements. Jointing material used shall be indicated on the Drawings. a. Rubber Gasketed Joints: Rubber gasket joints for tongue and groove or bell and spigot pipe shall consist of an O-ring rubber gasket or other approved gasket configuration and shall conform to the requirements of the appropriate ASTM Specification of the pipe designated. Unless otherwise approved by the ENGINEER, the standard joint configuration shall be similar and equal to the Bureau of Reclamation's "R-4" joint designation. Gaskets: Gaskets may be either natural rubber or neoprene conforming to ASTM Designation C-443. All gaskets shall be stored in a cool place, preferably at a temperature of less than 70 degrees Fahrenheit (F.), and in no case shall the gaskets be stored in the open, or exposed to the direct rays of the sun. No gaskets that show signs of deterioration, such as surface cracking or checking, shall be installed in a pipe joint. The neoprene gaskets used when the air temperature is 10F or lower, shall be warmed to temperature of 60F for a period of 30 minutes before being placed on the pipe. b. Mortared Joints: Mortared joints shall only be used in special circumstances and only where specifically authorized by the ENGINEER. It is the intent of these Specifications to limit the use of Mason SW Rehab Reinforced Concrete Pipe May 2012 02610-3 mortared joints to the minimum extent possible except where unusual field conditions require deviation from the jointing material specified. C. Flexible Plastic Joint Sealing Compound: Flexible plastic joint Sealing compounds shall not be used. e. Shop Drawings: Unless otherwise specified, the CONTRACTOR shall submit to the ENGINEER for approval shop drawings showing the exact dimension of the joints including the permissible tolerances for each size of pipe being furnished and the size, type and locations of gasket materials. Approval of the joint detail drawings will not relieve the CONTRACTOR of any responsibilities to meet all of the requirements of these Specifications, or of the responsibility for correctness of the CONTRACTOR's details. f. Acceptable Joint for Concrete Storm Installations: Except where a specified type of pipe joint or jointing material is noted on the Drawings, joints and jointing material for concrete sewer installations shall be Bell & Spigot w/B.O.R.Type R-4 Joint (ASTM C-361) or Bell & Spigot w/B.O.R. Type R-2 Joint. In addition to the gasket requirements, if the average joint gap in 36-inch diameter pipe or larger pipe exceeds 3/< inch, the void shall be filled and troweled smooth with an approved non-metallic, non -shrink grout conforming to ASTM C-827 or flexible plastic sealant conforming to Federal Specification SS-S-00210 so to provide a smooth interior surface at the joint. For pipe sizes 18-, 24-, 27-, 30-, and 36-inch in diameter, the reinforcement in the bell and spigot shall conform to ASTM C-76 for the class of pipe specified or to ASTM C-361 for a minimum pressure head of 25 foot, whichever is greater. 11. Protective Coatings: Normally, no additional exterior or interior protective coatings will be required for concrete pipe. However, whenever adverse corrosive conditions warrant additional interior protection, those pipe segments will be noted on the Drawings. PART 3 EXECUTION 3.01 SURFACE PREPARATION A. Within Easements, Cultivated, Landscaped, or Agricultural Area: All vegetation, such as brush, sod, heavy growth of grass or weeds, decayed vegetable matter, rubbish and other unsuitable material within the area of excavation and trenchside storage shall be stripped and disposed of in accordance with the requirements of Section 02230. Topsoil shall be removed from the area to be excavated and stockpiled, or, the CONTRACTOR may elect to import topsoil to replace that lost during excavation. Mason SW Rehab Reinforced Concrete Pipe May 2012 02610-4 Topsoil shall be removed to a depth of 8 inches or the full depth of the topsoil, whichever is less. B. Within Unpaved Roadway Areas: The CONTRACTOR shall strip the cover material from graveled roadways or other developed, but unpaved traffic surfaces to the full depth of the existing surfacing. The surfacing shall be stockpiled to the extent that it is acceptable and useable for restoration purposes. C. Within Paved Areas: The removal of pavement, sidewalks, driveways, or curb and gutter shall be performed in a neat and workmanlike manner. Pavement, sidewalks, driveways, or curb and gutter shall be cut with a power saw, pavement breaker, or other approved method of scoring, to a minimum depth of 2", prior to breaking or excavation. The pavement shall be cut vertically, in straight lines and avoiding acute angles. Any overbreak, separation, or other damage to the existing bituminous or concrete outside the designated cut lines shall be replaced at the CONTRACTOR's expense. Excavated paving materials shall be removed from the job site and shall not be used as fill or backfill. 3.02 DEWATERING A. All pipe trenches and excavation for structures and appurtenances shall be kept free of water during pipe laying and other related work. The method of dewatering shall provide for a dry foundation at the final grades of excavation in accordance with Section 02240. Water shall be disposed of in a manner that does not inconvenience the public or result in a menace to public health.

Concrete vibrators of lesser capacity are unacceptable for use in any part of the construction. The CONTRACTOR shall have at least one standby concrete vibrator ready for use for every two concrete vibrators in use during a concrete placement. PART 3 EXECUTION 3.01 PRIOR TO PLACEMENT Prior to placing concrete the CONTRACTOR shall remove all debris and thoroughly dampen the surfaces that will be in contact with the concrete to be placed. The CONTRACTOR shall use compressed air from an air -compressor to blow-out construction debris and dirt at the bottom of members to be placed such as walls, beams and columns, prior to final placement of forms that will obscure any joint. The CONTRACTOR shall demonstrate to the ENGINEER that all debris, such as concrete particles, saw dust, loose tie wire, bar tags, tape, trash and dirt, have been thoroughly removed. No concrete shall be placed when form surfaces that will be in contact with the concrete, reinforcement, embedded items or sub -base is less than 32°F. When the mean daily outdoor temperature is less than 40°F, the temperature of the concrete shall be maintained between 50OF and 70OF for the required curing period. When necessary, arrangements for heating, covering, insulating, or housing the concrete work shall be made in advance of placement and shall be adequate to maintain the required temperature without injury due to concentration of heat. Combustion heaters shall not be used during the first 24 hours unless precautions are taken to prevent exposure of the concrete to exhaust gases which contain carbon dioxide. Mason SW Rehab 03310-7 Structural Concrete May 2012 Concrete shall not be placed against forms exposed to heating by the unless the temperature of the forms is first cooled to <_ 90°F. 3.02 PLACEMENT Placement shall conform to ACI 301, Chapter 8 "Placing", ACI 304R, "Guide of Measuring, Mixing, Transporting and Placing Concrete," ACI 306 'Recommended Practice for Cold Weather Concreting", ACI 305 'Recommended Practice for Hot Weather Concreting" and ACI 309, "Standard Practice for Consolidation of Concrete". No concrete shall be placed until all formwork, reinforcement, installation of parts to be embedded, bracing of forms, and preparation of surfaces involved in the placing have been reviewed by the ENGINEER. No concrete shall be placed in water except with the written permission of the ENGINEER. All surfaces of forms and embedded materials that have become encrusted with dried mortar or grout from concrete previously placed shall be cleaned of all such mortar or grout before the surrounding or adjacent concrete is placed. Immediately before placing concrete, all surfaces upon or against which the concrete is to be placed shall be free from standing water, mud, debris or loose materials. The surfaces of absorptive materials against or upon which concrete is to be placed shall be moistened thoroughly so that moisture will not be drawn from the freshly placed concrete. The concrete shall be placed by equipment that will prevent segregation or loss of ingredients. The stream of concrete shall not be allowed to separate by permitting it to fall freely over rods, spacers or other embedded materials. No wetting of concrete surfaces during slab finishing operations shall be permitted. Further, no concrete finishing operation shall be permitted while there is water on the surface of slabs and other flatwork. Unless otherwise called out in these Specifications or shown in the Drawings, the placement lift depth of concrete in walls shall be limited to two feet or less to minimize surface defects such as air voids that can form on concrete surfaces. Lift depths will be limited to one foot if, in the opinion of the ENGINEER, the quality of the finish is unacceptable at the 2-foot lift depth. 3.03 CONSOLIDATION All concrete shall be thoroughly consolidated with internal vibrators as recommended in ACI 309 immediately after deposition. The concrete shall be thoroughly worked around the reinforcing steel, around embedded items and into corners of forms. Vibration shall be supplemented by spading, rodding or forking to eliminate all honeycomb and voids around embedded items. The vibrator shall be inserted vertically, allowing it to penetrate rapidly to the bottom of the lift and at least six inches into the previous lift. The vibrator shall be held at the bottom of lift for 5 to 15 seconds. The vibrator shall be pulled up at a rate of about three inches per second. Mason SW Rehab 03310-8 Structural Concrete May 2012 The vibrator shall be inserted so that the fields of action overlap. The field of action is approximately eight times the vibrator's head diameter. Thus for a 2 1/2 inch diameter vibrator, the spacing of each insertion will be approximately 20 inches. Vibration shall be stopped when the concrete surface takes a sheen and large air bubbles no longer escape. Do not use a vibrator to move concrete horizontally. 3.04 OPENINGS AND INSERTS Pipe sleeves, inserts for pipe connections, anchors and forms for pipe holes must be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. In the event that openings are inadvertently omitted or improperly placed, the ENGINEER may require the concrete to be cored at the proper location. Filling of improperly placed openings shall be done with expansive grout or dry pack or mortar applied with an accepted epoxy adhesive. The surfaces of the opening shall be roughened prior to filling. 3.05 EMBEDDED ITEMS At the time of concrete placement, embedded items should be clean and free from mud, oil and other coatings that may adversely affect bonding capacity. Aluminum embedments shall be coated with a bituminous material to prevent electrolytic action between the embedded item and reinforcing steel that results in concrete deterioration. Embedment items shall be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. Contact between embedded items and reinforcing steel or tendon ducts is unacceptable and is not permitted. 3.06 CONSTRUCTION JOINTS The location of all construction joints will be subject to the acceptance of the ENGINEER. The surface of all construction joints shall be thoroughly cleaned and all laitance and standing water removed. Clean aggregate shall be exposed by abrasive blast cleaning. Wire brushing and air water jets may be used while concrete is fresh provided results are equal to abrasive blast cleaning. Construction joints shall be keyed at right angle to the direction of shear. Except'where otherwise shown on the Drawings, keyways shall be at least 1-1/2" in depth over at least 25% of the area of the section. 3.07 EVAPORATIVE RETARDANT The use of an evaporative retardant is required to assist in proper placement of concrete. See Section 03390. When an evaporative retardant is used, it shall be applied two times: after screeding and after the first floating operation. The retardant should be applied at a rate of one gallon of sprayable solution per 200 - 400 square feet by spraying with an industrial type sprayer. If the nozzle of the sprayer becomes plugged, the CONTRACTOR shall. clean, or replace, the nozzle. Under no circumstances shall the retardant be used except by spraying a mist with a nozzle. The retardant shall be applied in strict conformance with the manufacturer's Mason SW Rehab 03310-9 Structural Concrete May 2012 recommendations and agent. The use of ENGINEER. precautions. In no case shall the retardant be used as a finishing an evaporative retardant requires review and approval by the END OF SECTION Mason SW Rehab 03310-10 Structural Concrete May 2012 SECTION 03320 CONSTRUCTION JOINTS PART1 GENERAL 1.01 SECTION INCLUDES The CONTRACTOR shall supply all labor, tools, equipment and material for the prepa- ration of construction joints in concrete in accordance with these specifications and as shown in the Drawings.
