..., exhibit significant to moderate increase in E, and K with increase in saturation from dry to fully saturated state. Whereas, G marginally decreases or remains more or less unin- fluenced and decreases significantly due to moisture variation. The sandstone com- prising of siliceous clay as grain...

... Abstract Air-dry and water-saturated samples of a sandstone and a mudstone from the Upper Silesian Coal Basin, Poland, were tested under uniaxial compression conditions with the aim of revealing the effect of moisture on the deformability of these sedimentary coal measure rocks. The volumetric...

... as a part of weathering, can cause problems even with preparation of samples for testing. In contact with water, moisture of the material is changed and deterioration process is initiated. In order to overcome problem with sample preparation, additions to test procedure are proposed. Additions are tested...
