Point Load Strength Index of Half-Cut Core Specimens and Correlation with Uniaxial Compressive Strength

Rock Mechanics and Rock Engineering, 2020
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, 1991
Point-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 ...

Point load strength index of granitic irregular lumps: Size correction and correlation with uniaxial compressive strength

Tunnelling and Underground Space Technology, 2017
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.
