Generally an L Type Test Hammers is used. Conversion to rock strength (UCS) also rely on the mineralogy of the rock in question. Many conversion curves exist and can be loaded into the RockSchmidt for UCS conversion on site. Schmidt Hammers lend themselves to grading rock core in the lab and testing rocks in the field.Physical Testing Laboratory Services | CTLGroup,The CTLGroup Physical Test Labs can provide strength testing for any material. Our capacities extend to 10 million pounds of strength testing, and many of the standard tests used nation-wide were created in these same labs. When the question is strength and durability, test CTLGroup to push the limits.Direct shear test - Wikipedia,For rock the test is generally restricted to rock with (very) low shear strength. The test is, however, standard practice to establish the shear strength properties of discontinuities in rock. The test is performed on three or four specimens from a relatively undisturbed soil sample.
