Abstract: The article deals with the dependence of heat conductivity, density and bending strength in unburnt clay samples made of forming mass with 7% humidity and having 2% of sapropel additives on formation pressure of the samples; and the dependence of heat conductivity of samples on their humidity and formation pressure during the period of investigation. It is established that the samples, which are made of forming mass with 7% absolute humidity, are being formed at 16 MPa and higher formation pressure. Heat conductivity and bending strength of the samples formed at 16+35 MPa pressure increases enhancing formation pressure. Heat conductivity and bending strength of the samples formed at pressure over 35 MPa reduces enhancing formation pressure. When absolute humidity of a sample increases, heat conductivity also increases and increases the most to the samples formed at 35 MPa pressure. Absolute humidity of samples (Beta = 0.766) is more significant for the prognosis of heat conductivity than formation pressure (Beta = 0.326) of samples
