PORTLAND CEMENT CONCRETE

These specifications cover materials, classifications, mix designs, proportioning, and testing of Portland cement

concrete. All concrete shall be air entrained unless otherwise shown on the plans.

The 2009 Edition of the Oklahoma Department of Transportation Standard Specifications for Highway Construction

govern, approved by the U.S. Department of Transportation, Federal Highway Administration, January 4, 2010. All

references to the Oklahoma Department of Transportation Commission pertaining to the 2009 Specifications and

Standards shall be interpreted to mean the City of Ada. All references to the “Engineer” in the Oklahoma

Department of Transportation specifications shall be revised to read the “City of Ada - Public Works Director”, or

his designee. All references to the “State”, “Department”, “Highway Department” or “Transportation Commission”

shall be interpreted to be “the City of Ada - Public Works Division” or “City of Ada” as applicable. Within these

specifications the 2009 Edition of the Oklahoma Department of Transportation Standard Specifications for Highway

Construction shall hereinafter be referred to as the “2009 ODOT Specs”, and the City of Ada shall hereinafter be

referred to as the “City”.

Note: Fly ash meeting the requirements of the 2009 ODOT Specs Section 702, “Supplementary

Cementitious Materials” may be substituted for up to 20% of the required cement. Make cement

substitutions on a one-to-one basis by weight [mass].

1) Use the weight of each material to calculate the water to cement ratio (W/C) using the following equation:

W/C=Water/(Cement + Fly Ash)

Determine the water use by adding the water measured into the batch, the water used in admixtures, and the

free water on wet aggregate and subtracting the water absorbed by dry aggregate.

2) Ensure the slump reflects a workability appropriate for the application. If using a high-range water-

reducing admixture, limit the slump to a maximum of 9 in [230 mm]. A specified concrete slump to be

delivered to the site shall be ordered by a city representative that is within the range in Table 1 for the class

ordered. A minimal amount of water may be added once on site to achieve the needed slump for the work

to be performed. Water shall not be added in large amounts to achieve the slump ordered.

3) Compressive strength shall be based on the average of the results of three test cylinders. Table 2 lists the

proper uses for each class of concrete:

B) Proportioning

Design and produce concrete mixtures in accordance with Table 1, “Concrete Classes”. The mix design shall

be based on the absolute volume for the class of concrete specified and the consistency suitable for satisfactory

placement of the concrete. Proportioning of the coarse and fine aggregate shall comply with ACI 211.1. Fine

aggregate and the mixing water shall be kept to a minimum to ensure concrete of the required workability for

placement.

High early strength concrete shall be 3000 psi concrete that meets the minimum strength requirement within 72

hours of placement.

The following information is required for each mix design:

1) City identification included with each mix design designation

2) Name and address of producer

3) Mix design designation

4) Aggregate sources, gradation, moisture content, and saturated surface dry batch mass

5) Water source and test reports required by 2009 ODOT Specs Subsection 701.4, “Water”

6) Fine aggregate fineness modulus

7) Cement type and sources

8) Fly ash source, if used

9) Type of admixtures and sources

10) High Range Water Reducer, if used in accordance with 2009 ODOT Specs Subsection 701.03.C, “High

Range Water Reducer (HRWR) Concrete Mixture

11) Material proportions

12) Unit weight

13) Air content

14) Slump

15) Water to cement ratio

16) Compressive strengths at 7 days and 28 days

17) Compressive strengths at 72 hr for high early strength concrete

18) Flexural strength at 28 days or 56 days for Class A used for concrete paving

Submit new mix designs if:

• The City rejects the mix design

• Material sources change

• The mix design produces unacceptable workability or production test results

With the extended bids that the City uses, source substitutions are allowed, but the substitutions must be

submitted to the City for approval before using a new source.

(c) Base compressive strengths on the

average of three test cylinders.

(d) Base flexural strengths on the average of

two test beams.

D) Mix Identification - Reference authorized mix identifications on batch tickets, test results, reports, and

Portland Cement

Provide cement that meets the requirements of the 2009 ODOT Specs Subsection 701.02, “Portland Cement”.

Admixtures

Only admixtures approved in the mix design and included in the bid price shall be used in any concrete. No

admixtures shall be used to replace cement within the mix design. In using admixtures the producer shall:

• Accurately measure admixtures into each batch,

• Dispense admixtures in liquid form. Provide dispensers large enough to measure the quantity for each

batch. Unless liquid admixtures are added to pre-measured water, arrange the discharge to uniformly flow

into the water stream.

• Store admixtures to prevent freezing. Agitate admixtures to prevent solids from separating or settling. Do

not use air agitation.

• If more than one liquid admixture, use separate equipment to provide and dispense each admixture. Ensure

that admixtures are compatible when used in combination.

• Air entraining admixtures shall be added during batching only.
