Construction materials research laboratory

    “True TRC” LLC’s “Construction Materials Research Laboratory” is engaged in the following activities.



Construction materials study, testing and quality control/quality assurance

  • All types of analysis of raw materials (sand, gravel, crushed stone, clay, cement) used in construction work
  • Determination of concrete content (heavy and aerated concrete)
  • Daily and frequency quality control of samples taken from concrete pours of buildings and structures
  • Combination of concrete batching plant technology



Road materials study and testing

  • Analysis and frequency analysis of road and railway quarries, dams and paving materials (gravel, crushed stone, sand, mineral powder, cement, bitumen)
  • Determination of embankment structure (crushed stone foundation, cement-reinforced foundation, asphalt concrete, cement concrete)
  • Concrete, concrete structures, sand, gravel, crushed stone, cement analysis and input for bridges, pipes and drainage systems
