TECHNICIAN GRADE 1 PRACTICE
TEST EXAM
What must be done to the concrete
surrounding the temperature measuring
device after the device is submerged in the
fresh concrete. - answer-Gently press the
concrete around the temperature
measuring device at the surface of the
concrete
The sensor of the temperature measuring
device shall be submerged a minimum of
_____ in. [_____mm] into the freshly mixed
concrete. - answer-3 in. [75 mm]
,The temperature measuring device shall
have a capacity of measuring temperature
of freshly mixed concrete to +- _____
degrees F [+- _____ C] throughout a range
of _____. - answer-1 degree F [0.5 C], 30
degrees F to 120 F [0 C to 50 C]
The temperature measuring device shall be
calibrated _____, or whenever there is a
question of _____. - answer-Annually,
accuracy
The temperature of concrete may be
measured in a wheelbarrow. True or False?
- answer-True
The temperature of concrete may be
measured in a wall form. True of False -
answer-True
,A composite sample of concrete is
required even if the only purpose for
obtaining the sample is to determine
temperature. True of False? - answer-
False
What must be done to the sample container
prior to sampling the concrete? - answer-
Dampen (with water)
How long must the temperature measuring
device remain in the freshly mixed
concrete? - answer-At least 2 minutes but
not more than 5 minutes

the nearest _____ degrees F [_____ C] -
answer-1 degree F [0.5 C]
According to ASTM C1064, what is one
reason to take the temperature of
concrete? - answer-Verify conformance to
a specified requirement for temperature of
concrete
