THE THERMAL CONDUCTIVITY AND THE THERMAL RESISTANCE OF THE LAYER OF NON-AUTOCLAVED FOAM CONCRETE BASED ON MICROSILICA
Abstract and keywords
Abstract (English):
The article presents the results of measurements of thermal conductivity coefficients and thermal resistances of non-autoclaved foam concretes based on microsilica depending on their average density. It is experimentally established that reducing the grade of non-autoclaved foam concrete from D800 to D400 by increasing the porosity of samples leads to a decrease in the thermal conductivity coefficient by 2.4 times and an increase in the thermal resistance of the layer by 2.5 times.

Keywords:
thermal conductivity coefficient, thermal resistance of the layer, non-autoclaved foam concrete, microsilica.
