A review of the tensile strength of rock was conducted to determine the relationship between direct tensile strength (DTS) and Brazilian tensile strength (BTS) and to examine the validity of estimating tensile strength from other measured properties, such as the crack initiation (CI) threshold.

if a rock mass is cut by directional joint sets, the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under consideration. The modes of failure of intact rock are multiple. Rock can fail in tension, compression or shear.

Compressive Strength (UCS). It is one of the most basic parameters of rock strength, and most common determination performed for boreability predictions. The unconfined (or uniaxial) compressive strength (UCS) of a rock is a common measure of the strength of intact rock. It is normally measured on cylinders of rock core by

requirements of a structure. The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load
Abstract—The reliability of the nondestructive Schmidt - Hammer Test as a means of estimating the compressive strength of concrete is investigated by testing three groups of concrete cube specimens.
towards any other strength parameter. (Bishop, 1966). In the case of concrete, the compressive strength is the most commonly measured strength parameter and this is also true of rock specimens. For the uniaxial or unconfined compressive strength test a right circular cylinder of the

The compressive strength gives the stress that is needed to destroy the sample by crushing. There is a complication though. If the material is brittle, such as concrete then the point of failure is clear. The sample suddenly fractures, frequently quite explosively as the stored energy is released. However if the material is ductile then it will ...
