Uniaxial Compressive Strength - an overview | ScienceDirect

The average uniaxial compressive strength of Set A is approximately 33.3 MPa, which is close to the original compressive strength. A linear relationship was discovered between the strength and the number of segments. The uniaxial compressive strength of the sandstone specimens decreased with an increase in the number of fractures.
