Deposit concrete as nearly as practicable to its final location to avoid segregation due to rehandling or flowing. Maintain reinforcing in the proper position during concrete placement operation.

D. Placing Concrete in Forms: Deposit concrete in forms in horizontal layers not deeper

than 24 inches and in a manner to avoid inclined cold joints. Where placement consists of several layers, place each layer while preceding layer is still plastic to avoid cold joints. 1. Consolidate placed concrete by mechanical vibrating equipment supplemented by

hand-spading, rodding or tamping. Use equipment and procedures for consolidation of concrete in accordance with the recommended practices of ACI 309, to suit the type of concrete and project conditions. Lower frequency vibrators may be used with authorized 8 inches or greater slump concrete.

2. Do not use vibrators to transport concrete inside of forms. Insert and withdraw vibrators vertically at uniformly spaced locations not farther than the visible effectiveness of the machine. Place vibrators to rapidly penetrate the placed layer of concrete and at least 6 inches into the preceding layer. At each insertion limit the duration of vibration to the time necessary to consolidate the concrete and complete embedment of reinforcement and other embedded items without causing segregation of the mix.

E. Pump Placement:

1. Pump lines shall be operated on decks in a fashion that will not damage, depress, or displace reinforcing steel already in place. Use hangers, trestles, or brackets, where necessary, to prevent damage or displacement of forms or reinforcing.

2. Lines from pump to the placing area shall contain a minimum number of bends. 3. When short time delays occur because of concrete delivery, form repairs, or other

factors, pump shall be operated slowly to and fro to keep concrete in motion.

F. Cold Weather Placing: 1. Protect concrete work from physical damage or reduced strength which could be

caused by frost, freezing actions, or low temperatures, in compliance with ACI 306 and as herein specified. When air temperature has fallen to or is expected to fall below 40 degrees F, uniformly heat all water and aggregates before mixing as required to obtain a concrete mixture temperature of not less than 50 degrees F, and not more than 80 degrees F at point of placement.

2. Do not use frozen materials or materials containing ice or snow. Do not place concrete on frozen subgrade or on subgrade containing frozen materials.

3. Do not use calcium chloride, salt and other materials containing antifreeze agents or chemical accelerators, unless otherwise accepted in mix designs.

G. Hot Weather Placing: When hot weather conditions exist that would seriously impair the

quality and strength of concrete, place concrete in compliance with ACI 305 and as herein specified. 1. Wet forms thoroughly before placing concrete. 2. Do not use retarding admixtures unless otherwise accepted in mix designs.

3.07 CONCRETE FINISHING

A. Finish of Formed Surfaces:

1. Rough Form Finish: For formed concrete surfaces not exposed-to-view in the finish work or covered by other construction, unless otherwise indicated. This is the concrete surface, having the texture imparted by the form facing material





used, with tie holes and defective areas repaired and patched and fins and other projections exceeding 1/4 inch in height rubbed down or chipped off.

2. Smooth Form Finish: For formed concrete surfaces exposed-to-view, or that are to be covered with a coating material applied directly to the concrete, or a covering material bonded to the concrete, such as waterproofing, dampproofing, painting or other similar system. This is the as-cast concrete surface as obtained with selected form facing material, arranged orderly and symmetrically with a minimum of seams. Repair and patch defective areas and form tie holes with all fins or other projections completely removed and smoothed immediately after removal and, for form work not supporting weight of concrete, no later than 72 hours after placement.

3. Smooth Rubbed Finish: Provide smooth rubbed finish to scheduled concrete surfaces, which have received smooth form finish treatment, not later than the day after form removal. Moisten concrete surfaces and rub with carborundum brick or other abrasive until a uniform color and texture is produced. Do not apply cement grout other than that created by the rubbing process.

4. Grout Cleaned Finish: Provide grout cleaned finish to scheduled concrete surfaces which have received smooth form finish treatment. a. Combine one part portland cement to 1-1/2 parts fine sand by volume,

and mix with water to the consistency of thick paint. Blend standard portland cement and white portland cement, amounts determined by trial patches, so that the final color of dry grout will closely match adjacent surfaces using an approved bonding agent.

b. Thoroughly wet concrete surfaces and apply grout immediately to coat surfaces and fill small holes. Remove excess grout by scraping and rubbing with clean burlap. Keep damp by fog spray for at least 36 hours after rubbing.

B. Finish of Unformed Surfaces:

1. Unformed Surfaces Related to Formed Surfaces. At tops of walls, horizontal offsets and similar unformed surfaces occurring adjacent to formed surfaces, strike-off smooth and finish with a texture matching adjacent formed surfaces. Continue final surface treatment of formed surfaces uniformly across adjacent unformed surfaces, unless otherwise shown.

C. Finishing Floors and Slabs: 1. General: Comply with ACI 302.1R recommendations for screeding,

restraightening, and finishing operations for concrete surfaces. Do not wet concrete surfaces.

2. Scratch Finish: While still plastic, texture concrete surface that has been screeded and bull-floated or darbied. Use stiff brushes, brooms, or rakes to produce a profile amplitude of 1/4 inch in one direction.

a. Apply scratch finish to surfaces where indicated as well as surfaces to receive concrete floor toppings or to receive mortar setting beds for bonded cementitious floor finishes.

3. Float Finish: Consolidate surface with power-driven floats or by hand floating if area is small or inaccessible to power driven floats. Restraighten, cut down high spots, and fill low spots. Repeat float passes and restraightening until surface is left with a uniform, smooth, granular texture.

a. Apply float finish to surfaces where indicated as well as surfaces to receive trowel finish or to be covered with fluid-applied or sheet waterproofing, or built-up or membrane roofing.

4. Trowel Finish (exposed interior floor slabs): After applying float finish, apply first troweling and consolidate concrete by hand or power-driven trowel. Continue troweling passes and restraighten until surface is free of trowel marks and uniform in texture and appearance. Grind smooth any surface defects that would telegraph through applied coatings or floor coverings.





a. Apply a trowel finish to surfaces where indicated as well as surfaces exposed to view or to be covered with resilient flooring, carpet, ceramic or quarry tile set over a cleavage membrane, paint, or another thin-film-finish coating system.

b. Finish and measure surface so gap at any point between concrete surface and an unleveled, freestanding, 10-ft.-long straightedge resting on two high spots and placed anywhere on the surface does not exceed 1/4 inch.

5. Broom Finish: Apply a broom finish to exterior concrete platforms, steps, ramps, and elsewhere as indicated.

a. Immediately after float finishing, slightly roughen trafficked surface by brooming with fiber-bristle broom perpendicular to main traffic route. Coordinate required final finish with Architect before application.

3.08 CONCRETE CURING AND PROTECTION

A. General: Protect freshly placed concrete from premature drying and excessive cold or

hot temperature, and maintain without drying at a relatively constant temperature for a period of time necessary for hydration of cement and proper hardening. 1.
