Compressive strength of rocks - PetroWiki

Using this critical porosity, we derive a uniaxial compressive strength .....(5) This C 0 equation is plotted in Fig. 2 along with the modified Scott and Jizba equations and data of Dobereiner and DeFreitas. Compaction strength. After a threshold region the rock begins to show ductile deformation under confining pressure.

Crushing strength | geology | Britannica

In compressive strength test The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.

Standard Test Methods for Compressive Strength and Elastic ...

5.2 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. Deformation and strength of rock are known to be functions of confining pressure.

IMPACT OF PHYSICAL AND MECHANICAL PROPERTIES OF ROCKS ON ...

was higher compared to the crushing of sedimentary rocks. It was also found that the hardness showed no significant influence on the crushing energy. Olaleye (2010) found that the increasing uniaxial compressive strength increased the time required for crushing. Toraman et al. (2010) conducted tests on laboratory jaw crusher and found a link between the crushing index and the impact strength index.
