Thermal analysis for Building Materials
The number of building materials used for construction purposes increases with the fields of application. This also increases the need to be able to make informed statements regarding the properties of the various media and compliance with the standards. The inspection of building materials not only ensures that all requirements of applicable laws and regulations are met. Documented safety standards also reduce the liability risk of all those involved in the construction project.
Simultaneous Thermal Analysis (STA) is ideally suited for the investigation and characterization of building materials such as concrete, cement, mortar, and other mineral building materials. Glass transitions of modified glass, binder burnout, and decomposition behavior can be analyzed, as well as the degree of cement hydration along with expansion and shrinkage.
Compared to an analysis using two separate devices, the STA has the great advantage of measuring weight change and the caloric reaction simultaneously. The same experimental conditions (atmosphere, heating rate etc.) apply to thermogravimetry (TGA) and differential scanning calorimetry (DSC). This allows significantly more accurate examination results and a greater information gain.
Dilatometry can provide essential information relative to expansion and shrinkage behavior of building materials during their production process and at their final location.
Determination of thermal conductivity with a HFM-Heat Flow Meter or LFA-Laserflash of building materials becomes more and more crucial as the demand for insulation materials and energy savings increases.
