Laboratory investigations, material testing
In cooperation with research institutes and testing laboratories of excellent reputation we execute mineralogical, chemical and
techno-physical analyses of rocks, industrial minerals and ores. In context with these investigations we can fall back on a long-term scientific experience and highly
sophisticated analyzing and testing methods.
We investigate the mineral content and the rock fabrics, analyze the chemical composition, measure porosity characteristics and
determine the strength behavior. Aside from this we test the weathering resistance and carry out wear tests. All results are evaluated due to the problem, edited and if
necessary documented in certificates. If required we get in contact with institutions which offer further analytical and investigation methods.
Our services include:
Mineralogical investigations
- Determination of the mineral content, classification of the rocks
- Structural analysis (grain size, granulometry, textures etc.)
- Investigation of the matrix and the matrix content
- Determination of clay minerals
- Analysis of salt minerals, identification of damaging minerals (newly formed minerals)
Chemical analyses
- Determination of main- and trace elements
- Eluation tests for the investigation of the environmental compatibility
Techno-physical investigations
- Determination of the density, dry bulk density, porosity, pore surface
- Porosity analysis (pore distribution, median pore radius)
- Strength properties (compressive strength, tensile strength, modulus of elasticity)
- Deformation properties (hygric swelling etc.)
- Thermal properties
- Water transport (water absorption and evaporation)
- Weathering investigation and tests (freeze-thaw-cycling test, salt crystallization, combined testing, weathering simulation)
- Abrasion resistance
- Surface properties (color, luster, roughness)
Analytical techniques
- Investigation of thin- and polished sections
- Scanning electron microscopy with EDX
- X-ray diffraction
- Microprobe analysis
- Atomic absorption spectrophotometrie (AAS)
- X-ray fluorescence (XRF)
- ICP-AES
- Mercury porositmetry
- Nitrogen-adsorption measuring unit
- etc.
