Test Procedure Impact for the Values of Specific Heat Capacity and Thermal Conductivity Coefficient

The basic condition of the correct proposal for thickness of the protective layer is knowledge of the temperature resistance of the material from which it is established or proposed to establish. It is necessary to know thermal conductivity coefficient λ of building material applied. The article is aimed at monitoring the impact of modification of test procedure of calorimetry on measured value of the specific heat capacity c and, then resulting values of thermal conductivity coefficient λ as well. The comparison of test procedures is made on three different building materials (sand, crushed aggregate fraction 0/32 mm, or 0/63 mm).
