    Crushed vs Round aggregate in concrete Structural

    Feb 03, 2012 Crushed vs Round aggregate in concrete. ACI 318-05 and -08 does not appear to reward the designer for specifying crushed aggregate over rounded usually river rock in structural concrete. Chapter 4 refers to ASTM C33, and leaves it at that. Certainly crushed rock has better interlock, and must have better shear friction for roughened surfaces.
