Thermal and Hygric Properties of a Carbon-Fiber Reinforced Cement Composite Material after Thermal Load
Original language description
Moisture diffusivity, high temperature thermal diffusivity, room temperature thermal conductivity, specific heat and water vapor permeability of a carbon fiber reinforced cement composite material are measured on specimens thermally loaded by subjectingto a temperature up to 1000 0C prior to the measurement. The linear thermal expansion coefficient is due to the character of the measuring method measured in the high temperature range to 1000 0C without any pre-treatment. The values of moisture diffusivity are found to depend on the thermal load in a very significant way, the maximum increase compared to the unloaded samples being two orders of magnitude. The changes of other studied parameters are lower but also significant. The water vapor permeability increases up to 4.5 times, the room temperature thermal conductivity decreases by 25% and the specific heat decreases by 20%
