requirements and other physical and chemical and uniformity
requirements for which tests can be completed by the time the
7-day lime-pozzolan strength test is completed. Release for
shipment and approval for use on the above basis will be
contingent on continuing compliance with the other requirements of
the specifications. If a bin fails, the contents may be resampled
and tested at the Contractor's expense. In this event, the
pozzolan may be sampled as it is loaded into cars, trucks, or
barges provided they are kept at the source until released for
shipment. Unsealing and resealing of bins and sealing of shipping
conveyances will be done by or under the supervision of the
Government. Shipping conveyances will not be accepted at the site
of the work unless received with all seals intact. If pozzolan is
damaged in shipment, handling, or storage, it shall be promptly
removed from the site of the work. Pozzolan that has not been
used within 6 months after testing shall be retested at the
expense of the Contractor when directed by the Contracting Officer
and shall be rejected if the test results are not satisfactory.
If tested pozzolan is rehandled at transfer points, the extra cost
of inspection shall be at the Contractor's expense. The cost of
testing excess pozzolan shall be at the Contractor's expense at a
rate of [_____] cents per ton of pozzolan represented by the test.
The amount will be deducted from payment to the Contractor.]
1.4.2
Construction Testing by Government
The Government will sample and test aggregates, grout, and
preplaced-aggregate concrete to determine compliance with the
specifications. The Contractor shall provide facilities and labor as may
be necessary for procurement of representative test samples. Samples of
aggregates will be obtained at the point of placement in accordance with
COE CRD-C 100. Grout will be sampled after the agitator and tested for
flow in accordance with ASTM C 939 and air content in accordance with ASTM
C 231. Unconfined compressive strength test specimens will be made and
cured in accordance with ASTM C 943 and tested in accordance with ASTM C
39/C 39M.
