compressive strength test of concrete introduction
Compressive Strength of Concrete | Definition, Importance ...
Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concrete's ability to resist loads which tend to compress it. The compressive strength of concrete is measured by crushing cylindrical concrete specimens in compression testing machine.

The power of compressive strength varies between and (SeshaPhani et al., 2013). The ratio of tensile strength to compressive strength also decreases as the compressive strength increases (Arιoglu et al., 2006, Lavanya and Jegan, 2015). It is worthy to emphasize that most of the relationships have been developed based on studies on the conventional vibrated concrete (VC).

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 ) makes a stronger concrete than a higher ratio. Concrete made with smooth pebbles is weaker than that made with roughsurfaced broken rock pieces for example.
