Crushed vs Round aggregate in concrete
Certainly crushed rock has better interlock, and must have better shear friction for roughened surfaces. I do not have the data, but I would bet crushed rock is better in most or all performance measures. The large aggregate (used in ready-mix concrete) in my area - Northern California - is either crushed 1"x#4 - or river rock 3/4".

Concrete Without Gravel
A typical concrete mix cannot be made without gravel. Concrete is made from a mixture of cement, sand, gravel (crushed stone), and water. A mix ratio of 1 part cement, 2 parts sand, 3 parts gravel, and water, will give you a strong concrete mix. If you subtract the gravel from concrete, you have what's called a mortar mix. Mortar mix is made ...
