Do not use materials containing frost or icy lumps.

Proportioning Grout Fill.

Fine concrete aggregate with 3 sacks of cement per cubic yard and a maximum slump of 6 inches.

3.1 Mixing

Plant Batched and Transit Mixed.

Batch at a central plant and mix enroute to the project in transit mix trucks in compliance with ASTM C94. (ASTM C94 Sections 3 and 17 shall not apply to this contract).

Place truck or transit mixed concrete within a maximum of 1-1/2 hours after introduction of cement into the batch. In hot weather or due to other contributing factors, a time less than 1-1/2 hours may be required by the COR.

Time interval between placement of batches not to exceed 30 minutes.

Plant Batched and Project Mixed.

Batch aggregates at a central plant and add water, cement, and admixture at the project.

Meet all requirements specified for transit mix.

Add cement, water, and admixture by accurate measurement, using measuring devices approved by the COR.

3.2 Project Batched and Mixed.

Batch and mix at project site.

Methods and apparatus used to batch the design mix will be reviewed for approval by the

COR.

Mixer rated capacity not to be less than a 1 bag batch. Batch quantities requiring fractional bags will not be allowed.

Mix concrete a minimum period of 1-1/2 minutes after all materials are in the drum.

Hand Mixed.

Hand mixing may be allowed only upon written approval of the COR. Batches not to exceed 1/2 cubic yard in volume.

3.3 Mix Adjustments

After the mix period but no later than 15 minutes from start of mixing, water may be added once for purposes of acquiring minimum slump, provided specified water-cement ratio is not exceeded. Adding water beyond these conditions constitutes retempering which will not be allowed. When water is added, an additional 20 revolutions at mixing speed is required.

Air-entraining admixtures will not be allowed to be added after the start of mixing for purposes of acquiring minimum air content.

3.4 Concrete Placement

Notify COR a minimum of 24 hours prior to placement.

Convey concrete from a mixer to the forms as near final position as practical in a manner which will prevent segregation or loss of materials.

Place concrete in maximum 18 inch horizontal layers.

Immediately after placing, thoroughly compact concrete with mechanical vibrators.

Hand tamping or "spudding" when permitted, will be approved in writing by the COR.

Footings may be placed separate from foundation walls. Provide minimum 2 x 3 x 18 inch key at 3 foot intervals.

Place each concrete section in a continuous operation, such as bottom slab, walls, and top slab.

Do not drop concrete freely from higher than 4 feet above the surface of concrete being poured.

Do not place concrete in water or allow water to rise over freshly placed concrete until a set is sufficient to prevent damage.

3.5 Seal Concrete Placement

Seal concrete may be deposited under water in a compact mass and in approximate horizontal layers without vibrating or tamping. Vibrate or tamp seal concrete when not placed under water.

Use tremie tube, closed bottom-dump bucket, or other means approved in writing by the

COR.

Tremie tubes shall be not less than 10 inches in diameter and bottom-dump buckets shall not be less than 1/2 cubic yard capacity.

Place point of discharge upon the prepared foundation or upon concrete already placed, then discharge and raise slowly during the discharge travel.

Avoid agitating the mixture or allowing water to enter the tube or bucket.

3.6 Protection from Rainfall

Protect flat work during periods of precipitation with adequate waterproof covering.

Support covering so that finishing may be performed and initial set obtained without damage. Dragging of tarpaulins or other covering across unset concrete will not be permitted.

3.7 Curing

Commence curing and protection of concrete immediately after placing. Cure Type I and Type II Portland Cement 7 days continuously and Type III Portland Cement 3 days continuously by one of the following methods:

Water Curing.

Keep all surfaces of concrete and forms left on concrete wet. Shade concrete from sun with covering material or with sand or sawdust on slab, except during periods of required finishing. Use of sprinklers or flooding is permitted on slabs.

Membrane Curing.

A liquid membrane-forming material may be used for curing at the Contractor's option, except on slabs receiving resilient floorings. Complete required surface finish prior to application of curing compound; use water curing during finishing period. Spray material to surface at the rate of 1 gallon per 300 square feet in 2 applications, resulting in a coverage of 1 gallon per 150 square feet. Apply first coat immediately after acceptance of finish. Thoroughly wet concrete with water and apply material just as surface film of water disappears. Apply second coat after first application has set. Recoat any rupture to the membrane seal immediately or use water cure method.

Cold Weather Concreting and Curing When descending air temperature at the project falls below 40 degrees F the Contractor may at their option, continue concreting under conditions stated below. Normal concreting operations may resume when the temperature at the site exceeds 40 degrees F.

Provide cover and heating equipment sufficient to maintain the temperature of the concrete at not less than 50 degrees F for a period of 3 days for Type I and Type II cement. Maintain the temperature at not less than 50 degrees F for a period of 2 days for Type III cement or when one additional sack of Type I or Type II cement is added.

Provide additional protection to prevent the concrete temperature from dropping more then 40 degrees F in the 24 hour period following the required protection period.

Keep all surfaces of concrete and any forms remaining on concrete wet. Remove and replace any concrete injured by frost and freezing as directed by the COR.

field quality control All tests will be performed by and at the expense of the Contractor. Concrete for the samples shall be provided by the Contractor at no additional cost to the Government.

Samples will be taken per each truck. If the measured slump falls outside the specified limits, a check test shall be made immediately on another portion of the same load. In the event of a second failure, the concrete shall be considered to have failed the requirements of the specification.

3.8 TESTING

The following concrete tests will be taken:

Slump.

Testing will be in accordance with ASTM C143. If the slump is greater than the specified range, the concrete will be rejected.
