1. To obtain a representative sample (concrete), take
several samples at three or more regular intervals
throughout the discharge of the mixer or truck.
DO NOT
take samples at the beginning or end of the discharge.
2. Dampen the inside of the cone and place it on a smooth,
moist, nonabsorbent, level surface large enough to
accommodate both the slumped concrete and the
slump cone. Stand on the “foot pieces” throughout the
test procedure to hold the cone firmly in place.
3. Fill the cone 1/3 full by volume (Figure 68-A) and rod
25 times with a 1/2” dia x 24” lg. bullet-pointed steel rod.
(This is a specific requirement which will produce non-
standard results unless followed exactly.) Distribute
rodding evenly over the entire cross section of the
sample.

4. Fill cone another 1/3 (Figure 68-B) which will make the
cone 2/3 full by volume. Rod this second layer 25 times
with the rod penetrating into, but not through, the first
layer. Distribute rodding evenly over the entire cross
section of the layer.
5. Fill cone to overflowing
(Figure68-C). Rod this layer
25 times with rod penetrating
into but not through, the sec-
ond layer. Distribute rodding
evenly over the entire cross
section of this layer.
7. Lift the cone ver tically
(Figure 68-E) with a slow even
motion.
DO NOT
jar the con-
crete or tilt the cone during
this process. ( Invert the with-
drawn cone, and place it next
to, but not touching the
slumped concrete.
6. Remove the excess concrete
(Figure 68-D) from the top of
the cone, using the tamping
rod as a screed.
8. Lay a straight edge (Figure 68-F) across the top of the
slumped cone. Measure the amount of slump in inches
from the bottom of the straight
edge to the top of the slumped
concrete at a point over the
original center of the base .
The slump operation must be
complete in a maximum
elapsed time of 1-½ minutes.
Discard the concrete.
DO NOT
use it in another tests.
