Physical and mechanical tests

We are skilled in physical and mechanical tests of fresh and hardened cement paste, mortar and concrete and the raw constituents (aggregates, additives, cement, etc.). Over many years of activity in the field we gained experience in methods according to various standards and recommendations. 

In addition to standard tests on fresh and hardened concrete and mortar, we are skilled in the following advanced techniques: 
  • Shrinkage and creep
  • Oxygen diffusion
  • AAR: Concrete-Performance-Test
  • Nitrogen-Sorption
  • Mercury Intrusion Porosimetry
  • Dynamic Vapor Sorption Analysis (DVS)
  • Plastic shrinkage
  • Autogenous shrinkage
  • Relative humidity evolution (self-desiccation and drying profiles)
  • Restrained shrinkage cracking (double-rings)
