Characterization of rock material by point load strength index test and direct cut
Minerva, 2021 The objective of this work is to establish a relationship between the cutting time in rocks, determining a speed and the point load strength index test, Is (50), to characterize the rock in terms of resistance and avoid sending samples to laboratories. As a first stage, on andesite samples, 5 x 5 x 10 cm test tubes were made. After the elaboration they

Journal of Korean Society For Rock Mechanics, 2012 Though the uniaxial compressive strength (UCS) of rock material is one of the key properties for rockmass characterization purposes, core samples for the test cannot always be obtained from the field. Indirect tests such as the point load test (PLT) can be a useful alternative.

Correlation between uniaxial compression strength and point load index for Irish Caledonian granites
, 2022 While the Uniaxial Compression Strength (UCS) test is the gold standard for determining the UCS of rock for geotechnical and mining applications, empirical correlations between UCS and other test measurements are useful in situations where intact cores are difficult to retrieve and/or the scope of UCS testing is constrained by budget.

Periodica Polytechnica Civil EngineeringPoint load test is a common, inexpensive and fast test for the indirect achievement of compressive or tensile strength of the rocks in the laboratory and the field. In this research, by conducting uniaxial compression test (UCT), axial (APLT), and diametral (DPLT) point load tests on gathered sulfate rock blocks from the Gachsaran Formation outcrops at
