Correlation between Uniaxial Compressive Strength and Point Load Strength of Penang Island Granites [PDF]
IOP Conference Series: Earth and Environmental Science, 2022 Abstract Uniaxial compressive strength (UCS) is one of the most widely used strength parameters in geotechnical design. The value is obtained through direct testing method, carried out through careful procedures of testing in a laboratory setting. As such, it is relatively more expensive, more tedious and requires longer time to complete.
