TY - CONF A1 - Kruschwitz, Sabine A1 - Strangfeld, Christoph T1 - Measuring screed moisture with EM methods – a comparison of capacitive Handheld and microwave resonator probes N2 - Measuring the moisture state of screeds is critical for floorers in order to prevent structural damages of bottom coverings. Typically destructive tests are carried out on small samples delivering only punctual information. We tested several non-destructive testing methods in terms of sensitivity in the critical low moisture range and observed substantially different drying behavior for the two tested cement based and calcium-sulphate based screed samples. Our findings are supported by moisture gradient measurements using the nuclear magnetic resonance technique. T2 - 11th Int.
