In the case of concrete that "sticks", the dark ceramic surface of the probe should be
wiped clean before each measurement to ensure that concrete residue "sticking" to the
surface of the probe does not falsify the measurement. Concrete with a flow class of
F2, F3 and F4 does not segregate so easily. Therefore, this measuring method of
inserting the probe at the side and tapping the side of the bucket to pack the concrete
delivers the best possible measurement results. For relatively stiff F2 concrete, it may
be necessary to place the bucket, together with the probe, on a shaking table to
compact the concrete before the measurement.
8.3.3 Measuring concrete with flow class F5 and F6
Very liquid concretes tend to segregate and there is the risk of larger parts accumulating
on the base of the bucket. Once the SWZ probe is inserted, fine particles can gather around
the surface of the probe and the values measured for the water content would be too high
as a result.
Therefore, the following procedure is recommended when measuring concrete with flow
class F5 to F6:
1. Fill 3/4 of a 12 l bucket with concrete
