Crushed vs Round aggregate in concrete - Structural .

Crushed vs Round aggregate in concrete - Structural .

Feb 03, 2012 · Here, the rounded aggregate is the stronger, more durable rock that is eons old. The crushed is usually limestone or pricey granite/basalt/trap rock. There is a big difference in placement and consolidation. There is always a consideration with the bond to smooth, old durable rock if you need unusually high compressive strengths.
