Outline of Final Research Achievements

1. Meteorological observation, field measurements of indoor and outdoor hygrothermal environment, non-destructive measurement of the moisture content of walls, continuous recording of salt damage of the wall, etc. have been carried out.
2. The sorption isotherm of salt-laden porous materials was measured and then modelled. The model was also combined with the classical independent domain theory to predict the hysteresis of sorption isotherm of salt-laden porous materials. The liquid water conductivity of salt-laden porous materials was also measured. Furthermore, the measurement device to measure the moisture properties of soil was successfully applied to measure that of stones.
3. Based on field investigation and measured material properties, moisture and salt transport in the material was predicted to propose a counter measure against salt damage.
