Dynamic compressive impact tests of building sandstone

·Yu et al [31] conducted dynamic impact tests on gray sandstone They found that grain size was correlated with the fragmentation of sandstone under a certain strain rate For sandstone buried deeply underground the dynamic behavior and fragmentation level closely correlate with the magnitudes of the pre stress and strain rate [21]
