batch in a portion of the mixing water. The solution shall be batched by means of a mechanical
batcher capable of accurate measurement.
3.1.6 Admixture may be added to concrete mixes to control the set, effect water reduction and increase
workability. The admixture shall be water-reducing normal or retarding admixture conforming to
ASTM C 494 but shall contain no calcium chloride. The required quantities of cement shall be
used in the mix regardless of whether or not any admixture is used. The quantity of admixture
used and the method of mixing shall be in accordance with the manufacturer’s instructions.
3.1.7 Fly Ash shall conform to ASTM C618 Type C or F.
3.1.8 Water, or other additives, added at the job site by the truck driver shall be the responsibility of the
providing company, unless directed by Light and Power personnel.
3.1.9 The temperature of the material, when off-loaded from the delivery truck shall not exceed 90°F. In
cold weather conditions, the temperature of material at the time of mixing shall not be less than
that indicated in the following table for corresponding outdoor temperature (in shade) existing at
the time of placement.
Table 1 – Concrete Temperature Requirements

4.0.2 Response time from order, to product delivery to the work site, shall not exceed 2 hours unless
agreed otherwise by Light and Power.
4.0.3 At the City’s option, it may be necessary for one delivery truck to be standing by at the work site
ready to unload upon completion of delivery from another truck.
4.0.4 A delivery ticket shall be prepared for each load of material delivered. A copy of each ticket shall
be handed to the Light and Power crew chief (or his designate) by the truck operator at the time
of delivery. Tickets shall show the mix identification, the number of cubic yards delivered, the
outdoor temperature in the shade, the time at which the cement was added, and the numerical
sequence of the delivery.
5. MIX DESIGNS
5.0.1 Mix designs shall conform to the performance requirements of Table 2 in this specification. A
written mix design of the bidder’s proposed material meeting those requirements shall be included with
the bid.
5.0.2 Design mix shall contain all admixtures required by these specifications and proposed by the
bidder to be used in the mixture.
5.0.3 In lieu of designing new mixes for each bid proposal, existing mix designs meeting all
requirements specified for each mix and used successfully on previous bids may be used
provided the following test information consistent with the requirements of Section 7 in this
specification is submitted with the bid proposal:
A. Report of mix design and previous test results for that exact mix.
B. Reports of at least 3 sets of 7 and 28-day compressive strength tests for ready-mix
concrete.
C. Reports of 3 sets of 24-hour and 28-day compressive strength tests for Flow-Fill backfill
mix made during the last six months.
D. Reports of compliance tests of fine and coarse aggregates made during the last six
months.

6. FIELD CONTROL TESTING
Tests, consisting of aggregate gradation tests, slump tests, air content tests, temperature testing, and/or
the securing of compression test cylinders, may be made at the discretion of Light and Power. These
tests will be performed by an independent testing laboratory selected by the city. The costs for field tests
will be borne by Light and Power, unless the tests show failure to meet specifications outlined in this
document. In the event of failure, the costs for testing, and all expenses incurred by Light and Power to
remove and replace the defective materials, if necessary, shall be borne by the company providing the
material.
