Triaxial shear test, A triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (eg, sand, clay) and rock, and other granular materials or powdersThere are several variations on the test In a triaxial shear test, stress is applied to a sample of the material being tested in a way which results in stresses along one axis being different from the .GCTS, Provides selection and design of laboratory and in-situ testing apparatus and software ranging from modification and adaptation of existing apparatus to the purchase of ,Rock Triaxial Test, The rock triaxial test was designed to determine the shear strength of rock sampl Different types of rocks have largely varying shear strength values, and the shear strength of a type of rock can vary greatly depending on its confining pressure, mineral structure, the moisture in the rock,USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL ,, Point load testing is used to determine rock strength indexes in geotechnical practice The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting In order to estimate uniaxial compressive strength, index-to-strength conversion factors are usedPOINT LOAD STRENGTH INDEX TEST OF ROCK (IS, Apr 28, 2014· The axial test is conducted on rock core sample of small length Minimum of 10 test specimens are required to find out the average value of point load strength index This test can be conducted on the core specimens which are completely dry or after soaking it for 7 days Measure the total length (l) and diameter (d) of the core specimen.
