Concrete made with quartz or basalt aggregate will have much higher compressive strength than concrete made with pea gravel. Cutting through harder concrete requires a wheel with a softer bond, which will constantly expose new abrasives. The Grit Tradeoff: Once you've decided on an abrasive, you'll need to pick a grinding wheel with the right grit.
