Correlation between uniaxial compressive strength and point-load index strength

In verifying the material properties of rock, laboratory test need to be carried out to ensure a safe design of structures. Among the most common rock properties verified in laboratory are uniaxial compressive strength test (UCS) and point-load index strength test (Is50). These two rock properties a...
