Abstract:
There are some attempts in this paper to overcome the difficulties in studying thermotechnical properties of heavy concretes. To exclude the influence of thermal contact resistance it is recommended to test the specimens of different thickness, placing the sample in intimate contact with the thermocouple and at last to use lubrication of the surface. Knowing the thermal conductivity of the lubrication and air one can calculate the real conductivity of a specimen under investigation.
