Concrete Compression Analysis - Santa Rosa Junior College

The ultimate strength of concrete is related to water/cement ratio and the size, shape, and strength of the aggregate used. Concrete with lower water/cement ratio (down to 0.35) makes a stronger concrete than a higher ratio. Concrete made with smooth pebbles is weaker than that made with rough-surfaced broken rock pieces for example.
