7. Report the results as the dierential between K and W, i.e.,
(e.g., K3.0 - W2.5 = 0.5).
8. Wash the tester with water.
9. The rst reading is approximately equivalent to the actual
ordinary slump, while the second reading (W) is a measure
of workability and compaction. The greater the value (W) is,
the better the workability and compaction of the concrete
will be. The dierential between K and W should NOT exceed
2.0 so as to minimize segregation.
10. The tester can be inserted in a compacted 6x12in (15x30cm)
cylinder, in buckets, wheelbarrows, ready-mix truck chutes,
slabs, columns, beams and any other desired location where
the fresh concrete is placed. Make sure there is a minimum of
6in (15cm) of concrete around the tester and that the oater
rests freely on the surface of the concrete. When the tester is
used in buckets, wheelbarrows and ready-mix truck chutes,
tamping gives a more uniform result.
11. If a tester is used in a standard cylinder, tap the cylinder lightly
(about 20 times) with the compacting rod or the tester to
close the hole that was left in the concrete upon removal
of the tester. The strength of the cylinder will be altered by
about 2% only.
OPERATING INSTRUCTIONS
1. Wet the tester with water and shake o the excess.
2. Raise the measuring rod, tilt slightly and let it rest on the pin
located inside the tester.
3. Level the surface of the concrete and insert the tester verti-
cally down until the disc oater rests at the surface of the
concrete.
NOTE: DO NOT rotate the tester while inserting or remov-
ing it from the concrete.
4. After 60 seconds, lower the measuring rod slowly until it rests
on the surface of the concrete that entered the tube and read
the “K-Slump” directly on the scale of the measuring rod. This
is the “K” value.
5. Raise the measuring rod AGAIN and let it rest on its pin.
6. Remove the tester from the concrete vertically up, and AGAIN
lower the measuring rod slowly until it touches the surface
of the concrete retained in the tube and read the workability
directly on the scale of the measuring rod. This is the “W” value.
