## Estimating uniaxial compressive strength of rocks using

Aug 01, 2013 Porosity is a significant physical feature of rocks due to water absorption that causes decrease in the strength. The basalt of the study area can be described as “highly porous” and ignimbrite as “extremely porous” according to the classification by Anon (1979).The average UCS of basalt is determined as 26.65 MPa.For the ignimbrite, the lowest UCS is observed in the black …

out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force. The tensile strength is then calculated as the failure tensile force divided by the cross-sectional area. It has been found that a rock core will split along a diameter when loaded on its side in a compression machine.
