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 ...

Improvements in the determination of point load strength
Bulletin of the International Association of Engineering Geology, 1985The point load test, developed over the last two decades, provides a practical and cheap method for laboratory or field determination of rock strength. Because of the size dependence of the test, results are corrected to a standard thickness of 50 mm and the resultant I(50) values may be used to estimate uniaxial compressive strength.

Study on the Relation between Uniaxial Compressive Strength and Point Load Strength
Applied Mechanics and Materials, 2014In 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.

New correlations between uniaxial compressive strength and point load strength of basalt
International Journal of Geotechnical Engineering, 2014AbstractAlthough the mechanical and physical properties of many rocks have extensively been studied, little work is reported on basalt rock. This paper discusses the interrelationships between the mechanical and the physical properties of the basalt rock.

Study on Rock Strength Characteristic by Point Load Test
Applied Mechanics and Materials, 2014Test point load test requires relatively small load, its instrument is portable, it can be easily applied to on-site testing,which may pave the way for the development of the fieldstrength of rock mechanics test, widely promoted in engineering construction, has a large space for development.

Point load tests and strength measurements for brittle spheres
International Journal of Rock Mechanics and Mining Sciences, 2009A multiaxial failure criterion for brittle materials is applied to a stress field analysis of a perfectly elastic sphere subjected to diametrically opposite normal forces that are uniformly distributed across small areas on the sphere's surface. Expressions are obtained for an intrinsic strength parameter of the material, as well as its unconfined ...
