Effect Of Weaker Rock Crushing Strength On Pavement Types Od Ball Mills

  • 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 ...

    In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes.

    compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.
