Physical testing - CRB

Physical testing

In addition to XRF analytics we determine the following physical parameter:

  • Moisture content, loss on ignition
  • grain size distribution by sieving
  • open porosity
  • water absorption
  • bulk density
  • apparent density
Physical testing bulk density, Loss on ignition, ash-content - CRB GmbH
