These characteristics will also govern rock behaviour and should figure prominently in any explanation of the interplay between landform evolution and rock type. Erosional agencies attack rock in a variety of ways such as by wear, abrasion, impact, crushing and plucking. The most important rock properties are those which reflect these processes.

ABSTRACT:. Uniaxial compressive strength (UCS) and Brazilian tensile strength (BTS) are widely used in rock engineering. However, preparing standard samples for the strength tests may not always be possible for weak rocks. On the other hand, only rock fragments are available to estimate the rock strength in some cases such as …
