..., aperture, filling, seepage, number of sets, block size and drill coring. Laboratory testing included: water content, porosity, density, absorption, swelling pressure, uniaxial compressive strength, point load test (PLT), Brazilian tensile strength (BTS) and direct shear test (DSH).

... Abstract For a better understanding of the directional strength behaviour of siltstone and shale rocks point load tests were carried out applying different load angles. For this purpose, the specimen had to undergo a special preparation procedure. Although, standard application recommendations...

... Abstract Tests on different types of effusive volcanic rocks under monoaxial loading conditions, such as uniaxial compression test (UC), point load test (PL) and indirect tensile test (B), are reported. The considered lithotypes span a wide range of porosity mostly due to macropores dispersed...

... of Queensland, School of Civil Engineering, Australia ABSTRACT: In this paper, an analytical solution is developed of the stress and displacement components in a three-dimensional solid disc subjected to Brazilian and point load test boundary conditions. The methodology is initially based on introducing...

... these weakness planes under uniaxial compression. It was experimentally demonstrated that the block punch test could be of similar importance as the point load test in estimating uniaxial compressive strength of schistose rocks. In case of these index tests, the stipulation of a valid specimen failure mode...
