Uniaxial compressive strength measurements of

2019-1-6  In many geo-engineering fields, the uniaxial compressive strength (UCS) of a rock material is the parameter most commonly used to define a rock’s mechanical strength. Several international standards have been developed for determining this value, which require the tested material to have certain minimum dimensions and shapes. In many applications, however, sample material is limited.

DETERMINATION OF UNIAXIAL COMPRESSIVE

Uniaxial Compressive Strength (UCS) defines mechanical strength of the intact rock material and it is one of the most used parameters in rock engineering. In the laboratory, it is determined by uniaxial compression on circular cylinder specimens according to standardized test procedures [1, 2].
