PART 3 EXECUTION

3.01 VAPOR RETARDER:

A. Install, protect, and repair vapor-retarder sheets according to ASTM E 1643.

3.02 STEEL REINFORCEMENT:

A. Comply with CRSI’s “Manual of Standard Practice” for vapor retarder before placing concrete.

1. Do not cut or puncture vapor retarder. Repair damage and reseal vapor retarder before placing concrete.

B. Joints: Locate and install construction, isolation, and contraction joints.

C. Concrete Placement: Comply with recommendations in ACI 304R for measuring, mixing, transporting, and placing concrete.

1. Consolidate concrete with mechanical vibrating equipment.

2. Screed and initial-float concrete surfaces using bull floats or darbies before excess moisture or bleedwater appears on the surface.

D. Finish formed surfaces as follows:

1. Rough-Formed Finish: Apply to concrete surfaces not exposed to public view.

2. Smooth-Formed Finish: Apply to concrete surfaces exposed to public view or to be covered with a coating or covering material applied directly to concrete, such as waterproofing, dampproofing, veneer plaster, or painting.

a. Apply smooth-rubbed finish to smooth-formed finished concrete.

E. Finished unformed surfaces as follows:

1. Scratch Finish: Apply scratch finisht to surfaces to receive concrete floor topping or mortar setting beds for ceramic or quarry tile, portland cement terrazzo, and other bonded cementitious floor finish, unless otherwise indicated.

2. Float Finish: Apply float finish to surfaces indicated, to surfaces to receive trowel finish, and to floor and slab surfaces to be covered with fluid-applied or sheet waterproofing, built-up or membrane roofing, or sand-bed terrazzo.

3. Trowel Finish: Apply a hard trowel finish to surfaces indicated and to floor and slab surfaces exposed to view or to be covered with resilient flooring, carpet, ceramic or quarry tile set over a cleavage membrane, paint, or another think film-finish coating system.

4. Trowel and Fine-Broom Finish: Apply a partial trowel finish, stopping after second troweling, to surfaces indicated and to surfaces where ceramic or quarry tile is to be installed by either thickset or thin-set methods. Immediately after troweling, and when concrete is still plastic, slightly scarify surface with a fine broom.

5. Non-slip Broom Finish: Apply a nonslip broom finish to surfaces indidcated and to exterior concrete platforms, steps, and ramps. Immediately after float finishing, slightly roughen trafficked surface by brooming with fiber-bristle broom perpendicular to main traffic route.

G. Concrete Protection and Curing: Protect concrete from cold or hot weather during mixing, placing, and curing.

1. Begin curing after finishing concrete, but not before free water has disappeared from concrete surface.

2. Cure formed and unformed concrete for at least seven days by moisture curing, moisture-retaining-cover curing, or curing compound.

H. Remove and replace concrete that does not comply with requirements in this Section.
