CSLB CONCRETE C8 LICENSE PRACTICE
EXAM WITH CORRECT ACTUAL
QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS LATEST ALREADY
GRADED A+
Which of the following is NOT a property of concrete? -
ANSWERS-High tensile strength
The concrete work is done in freezing zones, it gets cured by
______________. - ANSWERS-Steam
Explanation:
It is done by heating concrete by steam or using alternating
current, so that water content in the concrete is not
increased.
,Coarse aggregate in concrete is the material that is retained
in sieve number ____________. - ANSWERS-#4
Explanation:
The one which passes through sieve #4 is the fine aggregate.
All of the structural steel is considered satisfactory even if it
is rusted, but still meets the density requirements, except
___________________. - ANSWERS-Pre stressing steel
Explanation:
If the pre stressing steel is rusted, it cannot be used since it
does not meet the compliance requirements.
The compressive strength of concrete when treated with a
4" cube is always ____________ than when tested with a 6"
cube. - ANSWERS-More
The practice of making concrete to achieve the stipulated
minimum strength and durability and to make concrete in
the best economical manner is called _________________. -
ANSWERS-Mix design
, Explanation:
Mix design uses the theoretical calculations to get the
desired higher strength in concrete but yet consuming
minimum cement.
What is the purpose of using SCM in concrete other than
meeting workability requirements? - ANSWERS-To avoid
emissions:
The cement production is responsible for 7% of the
greenhouse gas emissions (GHG).
If the contractor has to transport the concrete, what is the
specified time for the concrete after catching under normal
circumstances? - ANSWERS-Before 1 1/2 hours
Explanation:
Or before 250 revolutions of the drum
What is NOT a key purpose in using SCM in concrete? -
ANSWERS-Short term curing period
The rough concrete finishes are generally appropriate for
surfaces subject to _______________. - ANSWERS-Traction
