Quality control from the start

In fresh concrete, water is required for the chemical reactions as the concrete sets. In the process, the mixture of cement and water hardens to form cement stone which then firmly binds the aggregate used.

Getting the right ratio of water to cement is important

The two scenarios below show what can happen if the water content is too high or too low.

How does it work?

The SONO WZ has been developed using radar technology for accurate results on site. A radar pulse is used to measure the moisture content in fresh concrete. The probe and handheld measuring device are designed for ease of use, so concrete batches can be tested quickly and safely, with minimal set up required.

A high-frequency TDR pulse is generated and runs along the probe, building up an electromagnetic field around the TRIME probe.

Data is collected as the pulse travels from the conductor and back to the source. The duration of the impulse along the measuring probe is directly linked to the volumetric water content, enabling results to be achieved within a couple of minutes.

 

Work with simple data

With the SONO WZ analyser, concrete can be sampled with a flow spread from F2 to F6. The test can be conducted by placing the concrete mix in commercially available 12-litre plastic buckets. The bucket should be ¾-filled with concrete.

Once the probe is inserted at the edge of the bucket, the test can start with a simple push of the button on the hand sensor.

The best results can be achieved through four to five individual measurements at different positions in the same bucket, i.e. each offset by 70° to 90°.

During each measurement, the concrete should be compacted by tapping the bucket on its side (e.g with the foot), to ensure the surface of the probe is fully covered by the mix.

After each individual measurement, the handheld measuring device displays the accumulated water content and calculates the mean value of the sample taken. The entire measurement procedure usually takes no longer than 2 minutes.

During testing, it is recommended that you tap the bucket to ensure the concrete
is compacted and the sensor is covered.
