DETERMINATION OF THE DIFFUSION COEFFICIENT OF NEW INSULATORS COMPOSED OF VEGETABLE FIBERS

Abstract

The knowledge of the moisture transport of building materials is necessary or the performance of building structures. The control of moisture transport s essential to describe the moisture migration process through the building alls. The present work's aim is to determine through experiment the water iffusion coefficient of different insulators in unsteady-state based on the ick's second law equation. This equation was solved analytically by the eparation of variables method (MOD1) and by the change of variables ethod (MOD2). The moisture diffusion coefficient for building material as experimentally predicted by using the weighing technique and different nalytical methods. The results were compared with experimental data.
