The point-load strength test

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1972
Abstract An index test for strength classification of rock materials is described. The test uses portable equipment. Specimens require no machining and can take the form of either rock core or irregular lumps. A single ‘point-load strength index’ can be obtained whatever the shape of specimen, provided that this shape is maintained within prescribed ...

Study on the Relation between Uniaxial Compressive Strength and Point Load Strength

Applied Mechanics and Materials, 2014
In order to investigate the relation between uniaxial compressive strength and point load strength, several homogeneous rock specimens were tested, and the influence of the different rock type was investigated using regression analysis and the derived equations were statistically tested.

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 ...

Experimental investigation of rock strength using indentation test and point load test

International Journal of Rock Mechanics and Minings Sciences, 2021
Various methods have been proposed to indirectly assess the uniaxial compressive strength (UCS) of intact rock when drilled cores are not available. Indentation test (IT) and point load test (PLT) are the two widely used methods in the field to assess ...
