摘要：
Long-term behaviour of a clay-bearing sandstone is investigated using elastic waves propagation coupled with strain measurements during moisture cycles. Adsorption and desorption are followed in a continuous way during several variations of relative humidity. Moisture adsorption is related to the solvation pressure and the measured elastic weakening during humidification is correlated with the clay minerals sensitivity.
