Effect of temperature on water vapour transport properties

Popis výsledku v původním jazyce

In this paper, the effect of temperature on water vapour transport properties of calcium silicate is studied, together with the influence of sample thickness. At first, the bulk density, matrix density, and total open porosity are measured for material characterization purposes. Then, sorption and desorption isotherms are measured using dynamic vapour sorption device in order to characterize the water vapour storage in re-searched material. The sorption process is analyzed for original material samplesas well as for finely ground samples in order to evaluate the effect of inner porous space on water vapour storage. The steady state cup method is used for determination of water vapour transport properties, whereas the measurements are per-formed at several temperatures and for three different sample thicknesses. The obtained data show an impor-tant effect of temperature on water vapour transport and storage in studied material. The results also indicate a substantial influence of sampl
