Zakres prowadzonych badań
Works in Materials Physics Laboratory are conducted in two basic directions:

  • mechanical properties testing;
  • widely understood effects related with heat and moisture flows.
Mechanical properties testing
We make investigations concerning:

  • compressive strength for loads ranging to 3000kN;
  • bending and compressive strength for loads ranging to 20kN;
  • Young’s modulus;
  • parameters describing properties of brittle materials;
  • velocity of ultrasonic wave propagation using the ultrasonic probe frequency 54kHz, 250kHz and 500kHz.
Heat and moisture flows
We make investigations concerning:

  • water vapour diffusion coefficient for gypsum, concrete, wood, mortars, building ceramics;
  • sorption isotherms in typical building materials;
  • absorbability of building materials;
  • measurements of heat flux.
Equipment
The most important devices in the Materials Physics Laboratory are:

  • Tonitechnik testing machine for measurements of compression strength, bending strength, Young`s modulus and yield point;
  • FEUTRON climatic chamber for simulation of influence of the surroundings on materials simulation;
  • infrared cameras VigoCam v50 and Testo 885 for detecting thermal bridges and evaluation of heat loss through the building partitions;
  • ALMENO digital recorder with humidity probe;
  • MYTRON climatic chamber;
  • MTA-10B humidity meter for measurements of relative humidity of concrete walls;
  • KFAP temperature and humidity meters;
  • HFM-3 heat flux meter for diagnostic of heat insulating power for building partitions;
  • Raynger pyrometer for contactless measurement of temperature of surface in maximum distance 30m;
  • SRH -77 and ITE thermohygrometers for measurements of temperature and relative humidity of air;
  • Mettler-Toledo PM-1200 and Radwag WPS 720C precise balances.
