Only loads which arrive in a satisfactory condition and which carry an inspection of delivery ticket will be incorporated into the work.

b. The Contractor will deliver and place concrete in the work within one (1) hour subsequent to the charging

03300-5 into the mixing drum, regardless of whether such mixing drum is part of a central plant or a transit mixer. This time shall be appropriately decreased when air temperatures are unusually high or the ingredients are such that an unusually quick time of set or loss of plasticity will occur, or during cold weather when loss of heat occurs to such an extent that the concrete will not be of the proper tempera-ture when placed in the forms.

e. The Contractor will convey concrete from mixer to forms as rapidly as practicable and by methods which will prevent segregation or loss of ingredients, will deposit the concrete as nearly as practicable in its final position, and will use chutes such that the concrete slides in the chute and does not flow.

Where a vertical drop greater than 5 feet is neces-sary, the Contractor will place the concrete through an elephant trunk or similar device to prevent segregation.

f. The Contractor will place concrete before the initial set has occurred, and in no event after it has contained its water content for more than one (1) hour. The concrete will be placed on clean, damp surfaces, free from water, or upon properly consol-idated fills, but never upon soft mud, dry porous earth, or frozen ground.

g. The Contractor will deposit continuously and as rapidly as practicable until the unit of operation is completed.

h. The Contractor will consolidate all concrete by vibration so that the concrete is thoroughly worked around the reinforcement, around embedded items, and

03300-6 into corners of forms, eliminating all air or stone pockets which may cause honeycombing, pitting, or planes of weakness. Mechanical vibrators with a minimum frequency of 7000 revolutions per minute, operated by competent workmen will be used.

i. In joining fresh concrete to concrete that has already set, the Contractor will remove all loose and foreign materials from set concrete, scrub with wire brooms and thoroughly clean the set concrete, and will moisten existing surfaces when the new concrete is placed.

j. Concrete in vertical members shall have been in place at least four (4) hours before concrete in horizon-tal, or vertical members resting thereon, is placed.

7. Weather Conditions:

a. Protection - The Contractor will:

(1) Provide adequate protection against rain, sleet and snow before and during placement and finish-ing of concrete.

(2) Provide adequate protective measures to maintain the temperature of the concrete as specified.

(3) Keep a thermometer on the job site at all times to record temperature.

b. Cold Weather Concreting - The Contractor will:

(1) Not place concrete when the atmospheric tempera-ture is below 40°F or when the concrete is likely to be subjected to freezing temperatures within 24 hours after it has been deposited unless adequate temporary heating is provided. In no case shall concrete be exposed to freezing temperature for 72 hours after placing.

(2) Maintain concrete temperature not less than 50°F nor more than 80°F for the first three (3) days

03300-7 after placing, and protect from freezing for the next five (5) days.

(3) Use no frozen materials or materials containing ice in concrete.

(4) Use no salt or other chemicals to prevent freezing.

(5) Perform all cold weather concreting in accor-dance with ACI 306, "Recommended Practice for Cold Weather Concreting".

c. Hot Weather Protection - The Contractor will:

(1) Not place concrete when the atmospheric tempera-ture is above 90°.

(2) Maintain concrete temperature not less than 50°F nor more than 90°F for the first three (3) days after placing, and protect from temperatures over 90°F for the next five (5) days.

(3) Thoroughly wet dry porous surfaces immediately prior to concreting.

(4) Perform all hot weather concreting in accordance with ACI 305, "Recommended Practice for Hot Weather Concreting".

8. Repairing and Patching - The Contractor will:

a. Remove and replace at no additional cost, any con-crete not formed as shown on plans, concrete out of alignment, surfaces beyond required tolerances, or defective surfaces which cannot be properly repaired or patched, including any concrete failing to meet the strength requirements.

b. Clean, dampen, and fill all bolt and tie holes and other similar defects, with patching concrete immedi-ately after removing forms.

03300-8

c. Remove to sound concrete all bulges, projections, honeycomb and all other defects in exposed concrete, and patch. Thickness of patch: 1-inch, minimum.

Cut the perimeter edges of all areas to receive patching mix perpendicular to the surface or under-cut. Feather-edge patches will not be allowed. Do all patching before concrete is thoroughly dry.

9. Curing - The Contractor will:

a. Protect concrete from premature drying. Provide temporary housing, covering, or other protection used in curing and keep in place and intact a minimum of 24 hours after artificial heating or cooling has been discontinued. Institute curing measures within two

(2) hours of finishing operations.

b. Keep concrete continuously moist for seven (7) days, and prevent rapid drying at the end of the curing period. Curing may be accomplished by one of the following methods.

(1) Use curing compounds conforming to ASTM

Specification C 309-5B, Type I. Do not use compounds on any surface which will receive additional concrete.

(2) Use non-staining polyethylene film and keep all joints weighted to prevent wind penetration.

10. Finishing:

a. A rubbed finish shall be given to all exposed walls above finish ground line. Fins and other projections shall be carefully removed and damaged places re-paired. After all required patching, cleaning, and correction of major imperfections have been completed, the concrete surface shall be rubbed with cement or carborundum bricks and water, leaving the surface uniformly smooth and clean.

b. Slabs - The Contractor will slope all concrete slabs in a manner to prevent the collection of water.

03300-9

1. Slabs and horizontal surfaces shall have a steel trowel finish unless specifically otherwise specified or directed by the Engineer.

2. All high areas shall be refloated to a uniform, smooth granular texture.

3. The finish surface shall be free of any trowel marks, uniform in texture and appearance. Floor surfaces not sloped as shown on the drawings shall be planed to a tolerance not to exceed 1/8-inch in 10 feet in any direction. Any surface defects of sufficient magnitude shall be removed by grinding.

c. Spreading dry cement for finishing will not be permitted.

11. Backfilling:

a. Walls shall not be backfilled for a minimum of ten

(10) days after placement, or until the concrete has reached 70% of its 28-day compressive strength as determined by cylinder break tests.
