We can build on the tradition of being initially a geological laboratory and can follow up on historical surveys, analyses and results.

We know that for our clients, it is essential to assess the effectiveness of the intended steps and procedures or the effect of the quality of raw materials on subsequent production.

Who are our clients?

  • Lime works, cement plants, glass works, quarries, manufacturers of building materials and products
  • Smelters, foundries, mining companies
  • Brick industry

What do we offer?

  • Tests of raw materials and division into types (types of clays, loess, soils...)
  • Technological tests of raw materials and mixtures for bricks
  • Granulometric analyses
  • Chemical analyses
  • Section and map construction (in cooperation with a partner company)
  • Estimation of raw material reserves (in cooperation with a partner company)
  • Drilling work (in cooperation with a partner company)
  • Resolution of conflicts of interests, changes to POPD (plan of opening, preparation and extraction) and DP (extraction area) (in cooperation with a partner company)

Granulometric analyses:

  • sieve analysis
  • Andreasen sedimentation analysis with determination of particles below 2, 2-20 and above 20 m

Technological tests:

  • determination of formation water
  • total drying shrinkage
  • firings at different temperatures
  • weight loss by burning
  • absorbency, apparent porosity
  • bulk density
  • capillarity, flexural strength when dry and after firing
  • deformation ratio according to Pfefferkorn
  • drying sensitivity according to Bigot
  • efflorescence
  • harmfulness of calcareous concretions

Chemical analyses:

  • Analysis of silicate materials according to a series of standards ČSN 72 0100 to 72 0121
  • Cation exchange capacities, loss on drying and annealing, etc.
  • Determination of the oxide composition (SiO2, Al2O3, Fe2O3, TiO2, MnO, CaO, MgO, Na2O, K2O, Li2O, …)
  • Free SiO2, total sulphur, sulphates, chlorides, fluorides, phosphorus, phosphates, organic substances, etc.
  • TC and TOC (total carbon and total organic carbon) – Act No. 383/2012 Sb.
  • Determination of trace elements after decomposition by ICP-OES, ICP-MS methods
