Hucka and Das stated that the concept of brittliness was not yet made precise.But with higher brittleness,the facts are observed,which include low values of elongation,fracture failure,formationoffines,high ratio of compressive to tensile strength,high resilience,higher angle of internal friction and formation of cracks in indentation.George defined that rock brattleness is the ability of a rock material to deform continuously and perpetually without apparent permanent deformations along witn the application of stress surpassing themicrocarcking of the material.A general law with regard to brittleness is that a more brittlerock breakes at very little deformation.Because the definition of brittleness only describes the behavior of rock deformation of rock deformstion and failure subjected to the concrete loading condeting,the mersurement of brittleness has not yet been standardardized.At present,five commen approaches are used to measure the brittleness calue.
