ABSTRACT
The presented work includes experimental data on the influence of lightweight filler on the thermal conductivity of λ gypsum. In this research, cenospheres were used. Cenospheres were added in the amount of 10% in respect to the mass of gypsum. To measure thermal conductivity, a non-stationary method was used based on the “hot wire method”. A decrease of thermal conductivity and density with added lightweight filler was observed because of microstructure modifications of the gypsum product. Additional microscopic images of the fractures of the modified gypsum were made.
