andesite compressive strength

Physical property relationships of the Rotokawa Andesite ...

We show that the strength, porosity, elastic moduli, and permeability are greatly influenced by pre-existing fracture occurrence within the andesite. Increasing porosity (or microfracture density) correlates well to a decreasing uniaxial compressive strength, increasing permeability, and a decreasing compressional wave velocity.

andesite compressive strength

andesite compressive strength. Rock properties - OoCities. 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.

Rock - Stress-strain relationships | Britannica

Rock - Rock - Stress-strain relationships: The deformation of materials is characterized by stress-strain relations. For elastic-behaviour materials, the strain is proportional to the load (i.e., the applied stress). The strain is immediate with stress and is reversible (recoverable) up to the yield point stress, beyond which permanent strain results.
