20-32 DETERMINAREA CONDUCTIVITĂŢII TERMICE A MATERIALELOR DE CONSTRUCŢII


ABOUT THE DETERMINATION OF BUILDING MATERIALS’
THERMAL CONDUCTIVITY
The paper introduces an experimental method of determining the
thermal conductivity of building materials. The installation we have created is
based on the Fouriér law allows the determination of the thermal conductivity of
the building materials’ which the test bars are made of, and implicitly, theirs
identification. This method does not allow an observation of the variation of
thermal conductivity with respect to temperature for the material under question,
the result of the analysis being in fact a mean value of thermal conductivity.
