Rock hardness is a term used in geology to denote the cohesiveness of a rock and is usually expressed as its compressive fracture strength. Terms such as hardrock and softrock are used by geologists to distinguishing between igneous/metamorphic and sedimentary rocks, respectively. These terms originated from historical mining terms, reflecting the methods needed to economically mine an ore ...

The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the Unconfined Compression Test is also …

Knowing the rock type and rock material hardness, it is possible for the experienced engineer or engineering geologist to make fairly accurate estimates on rock material strength. These can be readily verified by uniaxial compressive strength or point load tests. A simple estimate can be made from the field test in Table 5. The hammer tests ...

The uniaxial compressive strength decreases fastes at 100 °C, indicating that the variation of compressive strength is consistent with the fracture length density. This is because the fracture length density is the reflection of the total quantity of fractures, the more fractures inside of basalt, the lower compressive strength of basalt.
