Correlation of ultrasonic velocity slowness with uniaxial compressive strength of schists in Malaysia

The uniaxial compressive strength (UCS) of rock material is one of the important mechanical parameters widely used for design, analysis and modeling in geotechnical
engineering. Determination of UCS is destructive, expensive and time consuming. Recent
trends have shown that ultrasonic velocity testing is a viable option for the prediction of UCS,
considering that ultrasonic velocity testing is non-destructive, relatively inexpensive, fast and
easy to conduct.
