The point load strength index is a widely used index in rock engineering, and cylindrical core and irregular shaped specimens are used in its determination. But, in mine sites, the borehole cores are cut axially into two equal parts to obtain half-cut cores and one part of these half cores is sent to laboratory for geochemical analyses.

Point-load strength: An index for classification of rock material
Bulletin of Engineering Geology and the Environment, 1991Point-load strength (Is) as a measure for the determination of rock strength and for estimating uniaxial (unconfined) compressive strength (UCS) are described and both put together and used for rock strength classification of brittle and hard rocks. The estimated point-load strength values of specimens of varying sizes and also the values corrected to ...

Abstract The Uniaxial Compressive Strength (UCS) of rock cores is a key parameter for design analysis of rock engineering projects such as rock tunnels and piles in rockets. Diametral and axial point load tests on cylinder cores have been used to obtain Point Load Strength Index (PLSI). This PLSI is correlated to UCS.

The strength conversion factor (k) is the ratio between the uniaxial compressive strength (UCS) and the point load index (PLI). It has been used to estimate the UCS from the PLI since the 1960s. Many researchers have investigated the relationship between UCS and PLI for various rock types of different geological origins, such as igneous, sedimentary ...

Bulletin of Engineering Geology and the Environment, 2009
Uniaxial compressive strength and point load tests were carried out on 17 igneous, 16 metamorphic and 19 sedimentary rocks and the values correlated with their Is values. The influence of the different rock type was investigated using regression analysis and the derived equations were statistically tested.
