  • Summary

    25 10 2021  For measuring the coarse aggregate shape only the Multiple Ratio Shape analysis method MRA was the most appropriate and is much cheaper than all the other test methods Similar to the imaging systems the MRA provides the distribution of shape in an aggregate sample but it cannot be used for measuring angularity or texture.
