  • Strength Properties Of Rocks And Rock Masses 1

    In general, rock mass strength depends on the strength of intact rock and the strength of rockdiscontinuities. In general, compared to intact rock, a rock mass has reduced tensile strength(almost zero), and reduced shear strength especially along discontinuity planes. Further ,if a rock mass is cut by directional joint sets, the rock mass strength is anisotropic. Rock massstrength is scale dependent and varies with the volume of rock.

  • Building Stones: Meaning And Properties Geology

    1. Compressive Strength It is also sometimes referred as crushing strength of a stone and may be defined as the maximum force expressed per unit area, which a stone can withstand without rupturing. Any force applied beyond the compressive strength will cause a failure or rupture of the stone.

  • Lecture 9 – Introduction To Rock Strength David Hart

    That rock strength is affected by the SIZE of the specimen tested. This can be explained simply as being the result of the many flaws found in rock in the form of fissures, pores, cleavage, bedding planes, foliation, etc. The larger the size of the specimen tested the higher the probability that a weak flaw will be available, capable of.
