The temperature measuring device shall be cable of accurately measuring the
temperature of freshly mixed concrete to 1°F throught a range
of____________________________.-correct-answer-30 - 120°F
It is acceptable to measure the temperature of freshly mixed concrete in the
forms provided?-correct-answer-The sensor of the temperature measuring device
has at least 3 in. of cover in all directions.
Composite samples are required even if the only purpose for obtaining the sample
is to determine temperature.-correct-answer-False
The temperature measuring device is left in the freshly mixed concrete for at least
_______________ but not more than 5 minutes.-correct-answer-2 minutes
, 2|Page
Test Method C1064/C1064M specifies a maximum temperature of freshly mixed
concrete.-correct-answer-False
Given the following values, what us the Density (D) of the concrete?-correct-
answer-D = (Mc - Mm) / Vm
Mc = Mass of the measured filled
Mm = Mass of measure
Vm = Volume of Measured
A relative yield (Ry) greater than 1.00 indicates the batch to be "short" of its
designed volume.-correct-answer-False
Given the following values, what is the air content (A) of the concrete?-correct-
answer-A = [(T-D) / T] x 100
The Pressure Method for measuring air content of freshly mixed concrete is not
applicable to aggregates of high porosity.-correct-answer-True
