What standard is A23.2-1C? - Answers-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? - Answers-
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? - Answers-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? - Answers-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
When sampling for uniformity of mixed concrete, how
many sample should be taken and where? - Answers-
Three grab samples (not to be formed into a composite
sample).
Take them from widely separated portions of the batch
while the mixer is being completely emptied.
When collecting samples for uniformity testing in concrete,
how should the mixer be operating? - Answers-- Discharge
the concrete at the normal operating rate for the mixer
- Do not obstruct or retard discharge with an incompletely
opened gate or seal
, 3|Page
- Do not allow the mixer to turn in the mixing direction
between samples
- Do not add water to the batch once sampling has started
If you will be casting three 100mm x 200mm cylinders for
strength or uniformity testing, how much sample must be
collected? - Answers-A minimum of 20 L of mixed
concrete.
If you will be casting three 150mm x 300mm cylinders for
strength or uniformity testing, how much sample must be
collected? - Answers-A minimum of 30 L of mixed
concrete.
If you will be casting three 150mm x 150mm x 535mm
beams for testing, how much sample must be collected? -
Answers-A minimum of 55 L of mixed concrete.
If you are creating more than 3 samples (beams or
cylinders), how much more concrete sample do you need
to collect? - Answers-The volume of the extra specimens
plus 10%.
