Laboratory for concrete and cement

Basic activities of this laboratory are as follows:

  • Testing of physical and mechanical characteristics of non-hardened (fresh) and hardened concrete,
  • Testing of componental materials of concrete (cement, stone aggregate, water, additives),
  • Testing of influence of all types of additives on to the concrete quality,
  • Concrete production quality control on concrete plants (permanent and periodical control) (QC/QA) and control of production capability of concrete plants,
  • Quality control of component materials in concrete plants (permanent and periodical control) (QC/QA),
  • Preliminary concrete mixtures design (job mix trial) for concrete, mortar, injection mixtures and special concrete mixtures,
  • Evaluation of achieved compressive strength of concrete at the production process on concrete plants (statistical analysis),
  • Sampling at the construction site and concrete plants, curing and testing of concrete cubes as well as testing of already prepared and cured samples delivered by third parties,
  • Examination of physical and mechanical characteristics of cement, lime and gypsum,
  • Chemical testing of cement, lime and gypsum,
  • Analysis of usability and consulting services with the aim of improvement the quality at the production and placement of all types of concrete,
  • Analysis of usability and consulting services at using all types of cement,
  • Testing and certification of production of prefabricated concrete elements: hollow concrete tiles and bricks, concrete tile, concrete blocks and flat stones, concrete kerb etc.,
  • Testing and certification of: clay tile, clay bricks and blocks, solid and hollow bricks, lime silicate blocks and bricks etc.
