Testing of building materials

baustoffbild.jpgThe application of stones building materials is as old as the human being. Today the quality of building materials is a subject of austere rules and demands of standards. The independent testing and controlle of poducing building products by accreditated laboratories create confidence in applicating this products in civil-engineering.

  • Materials for building streets
  • Cement- and concrete testing
  • Self testing and external control

Sampling


Our works quality starts with sampling and goes with the raw material till to our laboratories

Detecting of the mineral phases:

If there is a certain amount of fines in the material and it should be used for base courses the detection of the mineral phases by XRD has to be done (X-Ray Diffraction) 

cement and concrete

Additionally a core sample can be taken and a specific investigation can be done.. 

recycled building materials
