Description
| - Thermal conductivity l, water vapor permeability d and liquid moisture diffusivity k of cement mortar are measured on specimens subjected to four types of pre-treatment, namely unloaded, mechanically loaded to 90% of compressive strength, thermally loaded by subjecting to a temperature of 800 °C for two hours, and loaded both mechanically and thermally. The values of l and k are found to depend very significantly on the loading mode. The maximum differences observed compared to the unloaded samples are almost one order of magnitude for l and as much as three orders of magnitude for k. In contrast, the values of d are found to increase by only about 40\% compared to the basic unloaded material. It is proposed that the observed large differences in l and k are due to the formation of cracks and the increase of total pore volume which were shown by visual analysis and mercury porosimetry
