Water-Saturated Sandstone

68% lower tensile strength

This sandstone exhibits a brittle-to-ductile transition under Brazilian splitting with varying water saturation, showing rougher fracture surfaces and reduced acoustic emission, offering new micro-macro correlations for assessing water-weakened rock stability.
