1.4 Batch Certification

Furnish with each load of concrete, a batch certificate containing all of the information shown on the example included at the end of this section.

Part 2 – Products

2.1 Cement

ASTM C150-76A Type II or IIA.

2.2 Aggregate

ASTM C33-74a with designated size of coarse aggregate No. 67 (3/4 inch to No. 4).

2.3 Water

Potable.

2.4 Admixtures

Air-entraining, ASTM C260-74, such as but not limited to “Protex”, “Darex”, “MB-VR”, “Castle-VR”, or “ADZ-Air”.

Admixtures other than air-entraining not permitted.

Hot Weather Concrete

The temperature of the concrete shall not exceed 80ºF. at time of placement, and when the ambient temperature reaches 90ºF., the concrete shall be protected with moist covering or other methods approved by the C.O.R.

Water, aggregate, and cement shall be protected or cooled as necessary. Ice may be used as part of the mixing water; however, the ice shall be completely melted by the time mixing is completed.

3.2 Mixing and Delivery

ASTM C94-74a, Sections 10.6 through 10.9, with the following additions:

1.

Adjust the quantities of aggregate and water to compensate for differences from the saturated surface-dry condition.

2.

Discharge concrete within 1-1/2 hours or before 300 revolutions of the drum after introduction of the mixing water to the cement and aggregates or introduction of the cement to the aggregates. If the ambient air temperature is above 80ºF., the above limits shall be 1 hour or 200 revolutions.

3.

If long hauling distance dos not permit meeting the requirements above, add cement and water to the truck mixer at the construction site.

3.3 Placing

C.O.R. must inspect forms before any concrete is placed. Notify C.O.R. at least 24 hours before any placement to permit inspection.

Roughen existing concrete surfaces.

Forms shall be free of debris, and surface shall be clean, free of frost, ice mud, and water.

Avoid segregation. Place in layers and begin placing at corners of structure. Do not move concrete with vibrators or tampers.

e.

Thoroughly work the external surface of the concrete with tools approved by the C.O.R. to force coarse aggregate from the surface and to bring mortar against the forms to produce a smooth finish, substantially free from water or air pocket or honeycomb.

Vibrating

Consolidate the concrete with suitable mechanical vibrators operating within the concrete.

Supplement vibrating by hand spading with suitable tools.

Vibrators shall be of a type and design approved by the C.O.R. and shall be so manipulated as to work the concrete thoroughly around the reinforcement and embedded fixtures and into the corners and angles of the forms.

Vibrate at any point sufficiently to accomplish compaction, but do not prolong to a point where segregation occurs.

3.5 Finishing

Slabs – Strike flush to within 1/8-inch variation in 10 feet. Lightly broom exterior slabs.

3.6 Curing and Hardening

Keep all concrete surfaces wet for 7 days after being placed. Acceptable methods include ponding, wet burlap, wet straw or hay, curing paper, plastic sheets, and membrane curing compound. Other methods must be approved by the C.O.R.

If wood forms are allowed to remain in place during the curing period, they shall be kept moist at all times to prevent opening at joints.
