Calculation of thermal conductivity coefficient of a binary mixture

A correct consideration of the thermal factors during design phase civil engineering structures in permafrost area determines their reliable and safe exploitation. Among important indicators selection solutions is conductivity coefficient construction materials used. The usually chosen from reference tables, but when using mixtures, determined through a calculation. aim present research was to compare calculated values binary mixtures (a mixture binding material filler) obtained Lichtenecker Schwerdtfeger formulas. comparison conducted range properties used for accumulation insulation mixtures. It that accumilation calculation results are quite similar within wide initial values. For significantly different. divergencies by hundreds percents. At current stage it impossible make conclusion about suitability either method determine mixture.
