Sampling from a Between 10% and 90% (Not when testing with Super
mixer/truck agitator- P)
Where is sample taken?
How is a sample taken Either pass a receptacle completely through a
when sampling plastic discharge stream OR divert a discharge stream
concrete? completely into a sampling container.
How many grab samples 3
are needed when testing
for uniformity of
samples?
What size sample is Minimum 20L
needed when casting 3
100mm x 200mm
cylinders?
What size sample is Minimum 30L
needed when casting
150mm x 300mm
cylinders?
What size sample is Minimum 55L
needed when casting
150mm x 150mm x 535mm
beams?
,How much extra sample Volume of the cylinders/specimens plus 10% extra
is needed when more
than 3
cylinders/specimens are
to be cast?
How much time is 10 minutes
allowed for obtaining,
transporting and
remixing the sample?
A sample contains It must be wet-sieved prior to testing
aggregate larger than
that appropriate for the
size of the moulds or
equipment.
Conc mix no, Sample source, Batch time/date,
Sample time/date, Project site, Sample location if
Information required on
different, Location of conc in structure, Technician
reports
name, Lab name/address, Signature of test report
reviewer, Any deviation from test procedures
The volume of air voids of plastic concrete,
exclusive of pore space in aggregate particles,
Air Content
determined through observations of the change of
air volume in concrete with a change in pressure.
A measure of consistency of freshly mixed hydraulic
cement concrete, equal to the subsidence,
Slump measured to the next 5mm, of the moulded
substance immediately after the removal of the
slump cone
The horizontal spread of concrete immediately
upon removal of the slump cone as a measure of
Slump Flow the unconfined fluidity of concrete giving a relative
degree of indication of the degree to which
concrete can travel
, How many water-to- 3
cementing materials
ratios are needed for
concrete trial mixes?
What temperature is 23 C +/- 2 C
considered stable before
mixing concrete?
Where should cementing In a dry place, in moisture-proof containers
materials be stored?
What sieve must 1.25mm or finer
cementing materials be
passed through before
use to reject lumps?
Surface moisture in fine 500g-1000g
and coarse aggregate
should be obtained using
samples of what size?
How much time is spent Mix 3 minutes, rest 3 minutes, mix 2 minutes
mixing concrete?
Which sample can be re- Slump or slump flow, NOT air. Must be remixed into
used for casting batch first
cylinders?
Must have nonabsorbent surfaces and be
Cylinder moulds
sufficiently rigid- Must be coated with mineral oil
Cardboard moulds Greater than 35MPa
cannot be used for what
strength?
Must be rectangular and 50mm longer than the
prescribed span. Must be watertight and rigid,
Flexural moulds
nonabsorbent. Variation from specified cross-
section is not to exceed 3mm. Coat with mineral oil.
Tamping Rod for 100mm Diameter 10mm +/- 1mm and a Length of 450mm to
x 200mm cylinders 600mm. One end must be hemispherical.
