GENERAL REQUIREMENTS:

Strength Requirements: Concrete slabs on-grade as indicated shall have a 28-day flexural strength of 650 pounds per square inch. Concrete made with high-early strength cement shall have a 7 day strength equal to the specified strength for concrete made with Type I or II portland cement.

Air Entrainment: Air entrainment shall be between 4 to 7 percent total air. Specified air content shall be attained at point of placement into the forms.

Special Properties: Concrete may contain other admixtures, such as water reducers, superplasticizers, or set retarding agents to provide special properties to the concrete, if approved.

Slump: Slump shall be within the limits of 3.5” to 5” for concrete as delivered to the point of placement.

NOTE: Where use of superplasticizers is approved to produce flowing concrete, the above slump requirements do not apply.

SAMPLING AND TESTING is the responsibility of the Contractor and shall be performed by an approved testing agency.

CERTIFICATES: Certified copies of laboratory test reports, including all test data, shall be submitted for concrete tests for review by the engineer.

CURING MATERIALS shall conform to the following:

MEMBRANE-FORMING COMPOUNDS: ASTM C 309, Type 1-D, Class A or B.

PREPARATION OF SURFACES: Surfaces to receive concrete shall be clean and free from frost, ice, mud, and water. Conduit and other similar items shall be in place and clean of any deleterious substance.

PLACING CONCRETE: Concrete shall be placed according to standard construction practices using any of the following methods:

Buckets: Bucket design shall be such that concrete of the required slump can be readily discharged. Bucket gates shall be “grout tight” when closed. The bucket shall provide means for positive regulation of the amount and rate of deposit of concrete in each dumping position.

Belt Conveyors: Belt conveyors may be used when approved. Belt conveyors shall be designed for conveying concrete and shall be operated to assure a uniform flow of concrete to the final place of deposit without segregation or loss of mortar. Conveyors shall be provided with positive means for preventing segregation of the concrete at transfer points and point of placement.

Pumps: Concrete may be conveyed by positive displacement pumps when approved.

Pump shall be the piston or squeeze pressure type. Pipeline shall be steel pipe or heavy duty flexible hose. Inside diameter of the pipe shall be at least three times the maximum size of the coarse aggregate. Distance to be pumped shall not exceed the limits recommended by the pump manufacturer. Concrete shall be supplied to the pump continuously. When pumping is completed, the concrete remaining in the pipeline shall be ejected without contaminating the concrete in place. After each use, the equipment shall be thoroughly cleaned. Flushing water shall be wasted outside the forms.

CONCRETE PLACEMENT: Mixed concrete which is transported in truck mixers or agitators, or concrete which is truck mixed, shall be discharged within 1 ½ hours or before the drum has revolved 300 revolutions, whichever comes first after the introduction of the cement to the aggregates. These limitations may be waived by the Government if the concrete is of such slump after the 1 ½ hour time or 300 revolution limit has been reached that it can be placed, without the addition of water to the batch. When the concrete temperature exceeds 85 degrees F. the time shall be reduced to 45 minutes. Concrete shall be placed within 15 minutes after it has been discharged from the truck.

Consolidation: Immediately after placing, each layer of concrete shall be consolidated by internal vibrators, except for slabs 4 inches or less. The vibrators shall at all times be adequate in effectiveness and number to properly consolidate the concrete. A spare vibrator shall be kept at the job site during all concrete placing operations. The vibrators shall have a frequency of not less than 8000 vibrations per minute, and the head diameter and amplitude shall be appropriate for this concrete mixture being placed. Vibrators shall be inserted vertically at uniform spacing over the area of placement. The distance between insertions shall be approximately 1 1/2 times the radius of action of the vibrator so that the area being vibrated will overlap the adjacent just-vibrated area by a few inches. The vibrator shall penetrate rapidly to the bottom of the layer and at least 6 inches into the preceding layer if there is such. Vibrator shall be held stationary until the concrete is consolidated and then withdrawn slowly. The use of form vibrators must be specifically approved. Vibrators shall not be used to transport concrete within the forms.

Consolidation equipment and procedures shall meet the requirements of ACI 309.

COLD WEATHER REQUIREMENTS: Special protection measures, approved by the

Contracting Officer or his or her representative, shall be used if freezing temperatures are anticipated before the expiration of the specified curing period. The ambient temperature of the air where concrete is to be placed shall be not less than 40 degrees F. The temperature of the concrete when placed shall be not less than 50 degrees F, nor more than 75 degrees F. Heating of the mixing water or aggregates will be required to regulate the concrete placing temperature.

Materials entering the mixer shall be free from ice, snow, or frozen lumps. Salt, chemicals or other materials shall not be incorporated in the concrete to prevent freezing.

CONSTRUCTION JOINTS shall be located as indicated or approved. Where concrete work is interrupted by weather, end of work shift or other similar type of delay, location and type of construction joint shall be directed by the project engineer subject to approval of the Contracting

Officer or his or her representative. Unless otherwise indicated, reinforcing steel shall extend through construction joints.

FINISHING CONCRETE: Finished concrete shall have a medium broomed finish.

CURING AND PROTECTION:

General: All concrete shall be cured by an approved method for the period of time given below:

Concrete with Type I or Type II cement 7 days.
