The Effect of Thermal Load on Hygrothermal Properties of Glass Fibre Reinforced Cement Composites
Original language description
The effect of thermal load on the basic thermal and hygric properties of three types of glass fibre reinforced cement composites (GFRCC) is analyzed in the paper. Thermal conductivity, specific heat and moisture diffusivity are determined after high temperature exposure to 600 and 800 C. The linear thermal expansion coefficient and the thermal diffusivity are determined in the high temperature range up to 1000 C. A decrease of thermal conductivity as high as 50% and an increase of moisture diffusivity in the range of one to two orders of magnitude are observed for all types of the studied materials after heating to 800 C. On the other hand, specific heat and density in the same situation decrease by only about 10%. An application of wollastonite and vermiculite is found to have a positive effect on the high temperature properties of the studied GFRCC compared to the usual sand aggregates
