b. Where laps are not shown on Drawings:

Bar Size 3 4 5 6 7 8 Minimum Lap, inches 20 20 26 33 45 59

2. Cleaning and Bending Reinforcement

a. When concrete is placed, see that metal reinforcement is free from ice, rust, mill scale, or other coatings that would destroy or reduce bond.

b. Bend bars cold. Do not field-bend bars partly embedded in concrete except as shown on Drawings or specifically permitted by ENGINEER.

3. Placing Reinforcement

a. Place reinforcement accurately according to Drawings, and adequately secured in position with concrete, metal or other approved chairs, spacers, or ties.

b. Protect reinforcement by concrete thickness shown on Drawings. Where not otherwise shown, minimum concrete thickness over reinforcement:

Concrete exposed to weather or soil: 1 ½” for #5 bars and smaller, 2” for larger bars.

Slabs and walls not exposed to ground or weather: ¾”.

In all cases, twice the diameter of the bars.

4. Splices in Reinforcement

a. As noted on Drawings, as specified, or as authorized by ENGINEER.

b. Do not weld crossing bars (tack welds).

C. Joints and Embedded Items

1. Construction joints

a. Locate construction joints only at designated control joints unless specifically approved by COR.

b. Continue reinforcement across joints. Provide longitudinal keys, ½” deep minimum. Clean and remove laitance from joint surfaces before placing adjoining concrete.

2. Control Joints (C.J.)

a. Locate as shown on Drawings.

b. In floors: Place control joint former after screeding. Remove top tear strip before floating.

3. Inserts and anchors

a. Drill and place anchors to secure posts to concrete as required and accurately placed for proper completion of other work.

D. Concrete Placement

1. General

a. Convey concrete from mixer to delivery place without materials separation or loss.

b. Use chuting, pumping, and pneumatic conveying equipment sized and designed for practically continuous concrete flow at delivery end without materials separation.

c. Use no re-tempered or contaminated concrete.

d. Deposit concrete as near as practical to its final position to avoid separation by re-handling or flowing.

e. Place concrete at a rate to assure plasticity and flow between bars.

f. Place concrete continuously until a panel or section is complete.

g. Thoroughly consolidate and vibrate concrete around reinforcement, embedded fixtures, and form corners.

h. Level, screed, and float concrete to a compact and dense surface free from low and high spots.

2. Curing compound: Spray one coat as soon as surface water has dissipated.

a. 200 sq. ft/gal on smooth surfaces. Increase coverage on textured surfaces.

b. Follow manufacturer’s precautions for protecting workers and the public.

3. Keep concrete moist at least 5 days after placement. Longer curing may be required when air temperature is below 50oF. Concrete may be covered with poly or wet burlap to help keep concrete moist.

E. Finishing Exposed Formed Concrete Surfaces

1. Fill holes immediately. Wet and rub exposed surfaces with a stone to a uniform color and texture without adding cement slurry and within one day of removing forms.

2. Where shown on Drawings, chamfer corner and edges; rub edges to ¾” radius.

3. Crown curbs.

F. Finishing Surfaces Not Cast Against Formwork

1. Initial: Do no finishing while free water is on the surface. Immediately after screeding, bull float slabs before excess moisture or bleeding water appears. When water sheen disappears, and concrete surface will support the operation, hand or machine float.

2. Tooled joints and edges, if used: Tool after initial set; retool after float if needed.

3. Final finish to meet descriptions on Drawings.

a. Broom Finish: After float finish, lightly draw a broom over surface and in the direction of the slope to form a textured finish. Retool joints and edges.

H. Cold Weather Requirements

1. Use no frozen, snowy, or icy materials. Use no salt or other chemicals to prevent freezing. Remove snow and ice from forms, reinforcement, fillers, and ground in contact with concrete.

2. Place only concrete with a temperature of at least 50oF in forms. Maintain concrete at 50oF or higher for 5 days, or longer if required to ensure adequate concrete curing.

3. Maintain housing, covering, or other protection for 24 hours after stopping artificial heating.

I. Hot Weather Requirements

1. Prevent concrete from drying before finishing operations.

2. Place concrete with a temperature below 90oF maximum and low enough to prevent flash set, cold joints, or loss of slump.

J. Tolerances

1. Plane surfaces: Within ¼” of a 10’ straight-edge in all orientations.

2. Grooved surfaces: 1” maximum variance in distance between grooves.

3.04 FIELD QUALITY CONTROL

A. Tests

1. Have tests performed by a testing laboratory acceptable to OWNER at CONTRACTOR’S expense.

2. Test and inspect concrete materials and operations as Work progresses.

3. Testing agency shall meet requirements of ASTM E 329.

4. Have testing agency review or check-test proposed materials and mix design for compliance with specifications.

5. Conduct concrete strength tests during construction:

a. Secure composite samples according to ASTM C 172. Take each sample at random from a different concrete batch. Select batch numbers at random before commencing concrete placement.

b. Mold and cure 3 specimens from each sample according to ASTM C 31.

c. Test specimens according to ASTM C 39. Test 1 specimen at 7 days for information and 2 specimens at 28 days for acceptance.

d. Acceptance test results: Average strength of two 28-day specimens, except discard results for a specimen evidencing improper sampling, molding, or testing.

e. Make at least one strength test for each 50 cubic yards, or fraction, of each concrete mix design placed in a day.

f. Determine slump for each sample and whenever concrete consistency appears to vary, using ASTM C 143.

g. Determine concrete sample air content as requested by ENGINEER using either ASTM C 173 or ASTM C 138. ENGINEER will require no more than 3 tests unless test results show abnormalities in air content.

h. Determine concrete temperature of each sample taken for strength test.

B. Site Observations

1. Notify COR at least 24 hours before a concrete pour.

2. Do not pour concrete without approval from ENGINEER.

3.05 ADJUSTING, CLEANING

A. Remove forms as soon as practical after placement.

B. Minor Defects: Repair surface defects, including exposed tie holes, immediately.

C. Major Defects

1. Surface defects deeper than 1” and greater than 1 sq. ft. in area are defective.

Remove and repair if requested by COR.

2. Floors designated as sloped on Drawings are defective if water remains standing on the surface. Remove and replace if requested by COR.

3. Honeycombed and other defective concrete: Remove down to sound concrete.

Chip edges perpendicular to the surface or slightly undercut; do not feather edges. To prevent absorption of water from grout, dampen an area to be patched, and a 6” area surrounding it.

4. Mix patching mortar in advance, mix frequently without adding water, and use when it has reached the stiffest consistency that permits placing.

5. After surface water has evaporated from surface to be patched, brush on bond coat.

Apply patching mortar when bond coat loses its water sheen.

6. Thoroughly consolidate mortar into place and strike off slightly higher than surrounding surface. Leave undisturbed for at least 1 hour before final finishing. Keep patch damp for 7 days.

7. Do not finish patches on exposed walls with metal tools.

D. Exposed tie holes: Clean, dampen, and fill solid with patching mortar.
