Correlation between uniaxial compressive strength and point load strength index of granite sample

Uniaxial compressive strength (UCS) of rocks is an important parameter in geotechnical structure designs. Being difficult to obtain proper sample and the UCS test itself is expensive, indirect methods of estimating UCS were developed such as point load test. In this study, an attempt has been made t...
