  • Crushed vs Round aggregate in concrete

    Feb 03, 2012 · Crushed vs Round aggregate in concrete. ACI 31805 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.
