Masonry 101: How to Repair A Concrete (Cinder) Block Wall ...
Concrete is is a lot coarser and includes large rocks and gravel. You can use mortar mix to repair masonry, but it is about 45x as expensive, and the finish isn't that much nicer. The correct ratio of concrete mix to water depends on your conditions, but it is always better to add it little by little, since it is easier to moisten dry mix then try to absorb excess water.
