Binding systems

Research and development of mortars

  • Basic and applied research in the branch of silicate technology
  • Design of optimal technologies in the branch of mortars and burnt products
  • Experimental and consultancy activity in the field of Portland clinker and cement quality
  • Assessment and conveniency testing of natural and secondary raw materials for clinker burning, cement production and other binding materials production
  • Conveniency assessment of limestone for lime burning and dolomites for half-burnt dolomite (PVD) burning
  • Conveniency assessment of lime for lime hydrate production, possibilities of model tests
  • Conveniency assessment of dolomites for industrial use
  • Conveniency verification of raw materials for production of lightweight clay artificial aggregate and expanded perlite

Testing laboratory of mortars

  • Verification and evaluation of the binding material quality according to standards CSN, EN and DIN and also according to customer´s methodology
  • Measurement of hydration temperatures course of hydraulic binders by means of adiabatic and semi-adiabatic calorimeter
  • Determination of cement hydration heat by dissolving method according to Czech standard CSN EN 196-8 and by means of differential calorimeter
  • Supplying of standards for calibration of Blaine apparatus used for specific surface determination
Differential calorimeter

Adjustment

  • Verification of physical-mechanical properties of raw materials from the point of adjustment process (determination of grindability according to Zeisel, VTI, abrasivity test etc.)
  • Crushing, milling and homogenization of specimens up to 100 kg
  • Sieve analyses on screening machine Alpine
  • Firing in laboratory kilns up to 1600 °C and in amount up to 1 kg
  • Flameproof finish of materials in model rotary kiln up to 1600 °C in amount 2 kg/h
