Test Reports
1.6.4.1
Concrete Mixture Proportions
a.
Submit copies of test reports by independent test labs conforming
to ASTM C 1077 showing that the mixture has been successfully
tested to produce concrete with the properties specified and that
mixture will be suitable for the job conditions. Test reports
shall be submitted along with the concrete mixture proportions.
Obtain approval before concrete placement.
b.
Fully describe the processes and methodology whereby mixture
proportions were developed and tested and how proportions will be
adjusted during progress of the work to achieve, as closely as
possible, the designated levels of relevant properties.
1.6.4.2
Fly Ash and Natural Pozzolan
Submit test results in accordance with ASTM C 618.
Submit test results
performed within 6 months of submittal date.
1.6.4.3
Ground Iron Blast-Furnace Slag
Submit test results in accordance with ASTM C 989 for ground iron
blast-furnace slag. Submit test results performed within 6 months of
submittal date.
1.6.4.4
Silica Fume
Submit test results in accordance with ASTM C 1240 for silica fume.
Data
shall be based upon tests performed within 6 months of submittal.
1.6.4.5
Aggregates
Submit test results for aggregate quality in accordance with ASTM C 33, and
the combined graduation curve for grading proposed for use in the work and
used in the mixture qualification, and ASTM C 295 for results of
petrographic examination. Where there is potential for alkali-silica
reaction, provide results of tests conducted in accordance with ASTM C 227
or ASTM C 1260. Submit results of all tests during progress of the work in
tabular and graphical form as noted above, describing the cumulative
combined aggregate grading and the percent of the combined aggregate
retained on each sieve.
1.6.4.6
Admixtures
Submit test results in accordance with ASTM C 494 and ASTM C 1017 for
concrete admixtures, ASTM C 260 for air-entraining agent, and
manufacturer's literature and test reports for corrosion inhibitor and
anti-washout admixture. Submitted data shall be based upon tests performed
within 6 months of submittal.
[1.6.4.7
Fiber-Reinforced Concrete
Test to determine flexural toughness index I5 in accordance with ASTM C 1116.
