Building Materials

Determination of thermoanalytical and thermophysical properties allows for the comprehensive characterization of building materials. Knowledge about such aspects as composition, mass loss (due, for example, to binder burnout), thermal expansion, sintering, softening point and thermal conductivity is critical in the development of new materials and helps to ensure that final products can meet the demands being placed upon them.

Simultaneous Thermal Analysis (STA) is ideal for investigating issues such as the glass transition temperature of modified glass, phase transitions in plasters and mortars, and thermal decomposition behavior – also with instrumentation for Evolved Gas Analysis (EGA) coupled to the thermal analyzer.

The expansion and shrinkage behavior of building materials, both during production and once in use, can be determined with Dilatometry.

LFA, HFM and TCT are versatile methods for the precise determination of thermal diffusivity and thermal conductivity on samples both small and large.

Refractories can be investigated with an instrument series that is specially tailored to this material group. This series is comprised of the apparatus for determining refractoriness under load (RUL) and creep in compression (CIC), the apparatus for testing hot modulus of rupture (HMOR), the thermal conductivity tester (TCT), and the pyrometric cone equivalent (PCE 428) apparatus.
