Determination of thermal conductivity by transient hot wire …

Thermal property data are important for the engineering solutions of the heat transfer problems. There are many cases in which thermal conductivity of the studied material is not available, eg. cement materials of different compositions during setting and hardening. Furthermore, these materials are wet and porous and in order to prevent development of humidity gradients under imposed thermal
