Original Abstract

The moisture diffusivity of three different carbon fiber reinforced cement composites is determined after pre-heating to 600C deg. and 800 C deg. and compared with the measurements of cumulative pore volume in the same conditions. The obtained results give a clear evidence that moisture diffusivity is a more sensitive parameter characterizing the thermal damage than porosity because it is able to indicate not only the change in the pore volume but also the appearance of cracks.
