This practice specifies procedures for laboratory rock core test specimen preparation of rock core from drill core and block samples for strength and deformation testing and for determining the conformance of the test specimen dimensions with tolerances established by ...

Soil and Rock Sampling Methods. The collection of representative subsurface samples is key to the development of relevant and accurate geotechnical evaluations and assessments. There are a wide variety of sampling methods available, and each is suited to a particular exploration method (s) and information goals.

The rock triaxial test was designed to determine the shear strength of rock samples. 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 .

Place the sample onto the stage of the mounting press, lowering the ram via the lever on the lower left of the machine. Pour in the appropriate amount of Bakelite. Place the press on top, screwing it on tightly, then loosening it a quarter turn (since there is a buildup of heat and pressure during the process). then place the ram lever into the "up" position and leave it there.

Samples shall be representative of the rock to be studied. Obtain samples by direct sampling of subsurface rock units with core borings or by sampling blocks of rock material from outcrops that correlate with the subsurface rock unit of interest. At surface outcrops, avoid sampling and testing rock material
