Scale Effect and Correlation between Uniaxial Compressive Strength and Point Load Index for Limestone and Travertine [PDF]

open access: yesApplied Sciences, 2021
Determining the uniaxial compressive strength of intact rock is the primary objective of a geomechanical project, and a reliable estimate in the early phases saves time and costs for more sophisticated laboratory tests.

The effect of non-standard loading platen usage on point load index value of rocks [PDF]

open access: yesJournal of the Southern African Institute of Mining and Metallurgy, 2021
The point load index is a simple, fast, and inexpensive method for determining rock strength and can be applied both in the field and in the laboratory. There are, however, some disadvantages and limitations to the method, and the test results can be affected by the person carrying out the test, the rock characteristics, or the test device.
