2019-5-24 · The present studied conducted for determining the shear strength characteristics of limestone, sandstone and gravel Shear strength decreases with increase in particle breakage or decrease in particle size. The magnitude of crushing increases with an increase in normal stress but major crushing occurs during shear The grain size distribution of the sample undergoes a continuous change with the application of shear and normal stress. For same particle size and gradation, shear strength of sandstones and gravel, are different at normal stress. At high normal stress, shear strength of gravel, is more than sand stone due to its lower crushability At high normal stress, the shear strength of lime stone is lower than sand stone and gravel because of its higher magnitude of crushed

Zhang  and Zhang et al. [25,26] put forward a fractal model for compaction and crushing of waste rocks so as to
-Most of the previous constitutive models used for investigation of the shear behavior of rock material have been developed without consideration of the oversize particles. The size of experimental samples is an important limitation in this case. In this research a laboratory study has been planned to investigate the shear strength of rock materials containing different gravel contents.
