Résumé:
This article presents a dual method for the determination of thermophysical and hydric properties of porous materials. First empirical relationships between thermophysical properties and moisture content were determined. Then, a laboratory setup allowed for temperature recording during a drying test. Empirical relationships and recorded data are the algorithm inputs. The two stages algorithm is based on a finite difference discretization and a parametric estimation. Autoclaved Aerated Concrete was tested in this case study and positive estimation results with 8 % accuracy are encouraging outcome for next use of the method.
