CCIL Certification EXAM Graded A+ with
Questions Solved 100% Correct
How can you ensure that your concrete cylinder for testing does not attach to the
mould? - Answer Lightly coat it with mineral oil or other suitable non-reactive release
material before use
What type of water is to be used in storage tanks for what used in concrete testing? -
Answer Water that is saturated with calcium hydroxide
For flowing superplactizied concrete with a large slump, how much the required
rod should you use while setting the sample in the cylindrical mould? - Answer 40%
, What is the relationship between the maximum nominal size of a coarse aggregate in
a concrete sample and the cylindrical or beam specimen size to be moulded? - Answer
The diameter of a cylinder or the minimum cross-sectional dimension of a beam must
be at least 3 times the maximum nominal size of the coarse aggregate in the concrete.
At what specified slump should a concrete sample be consolidated via rodding?
- Answer Greater than 40 mm slump
At what specified slump should a concrete sample be consolidated via vibration? -
Answer Equal to or less than 40 mm
What standard is A23.2-1C? - Answer Sampling plastic concrete - a test method that
specifies the procedures, location, and sample size required to obtain a representative
sample of fresh concrete and to assess its traceability to the structure it represents
(how to obtain a representative sample of fresh concrete from a truck agitator or mixer
At what discharge points should a fresh concrete sample be taken from a truck
agitator or truck mixer? - Answer Between the 10% and 90% points of discharge.
When should a fresh concrete sample not be taken from the 10% and 90% points
of discharge from a truck or agitator? - Answer 1) When it is required that concrete
be tested for slump immediately prior to the addition of superplasticizer
2) When precast concrete is produced in a stationary precast mixer
What is a grab sample and when is it used for concrete testing? - Answer Grab sampling
is the operation of securing at one point of the discharge the required volume of
representative material in as short a period of time as possible.
To evaluate for quality (strength and corresponding related plastic concrete
properties) - single grab sample in specific location
To evaluate for uniformity - three grab samples
