## What Does Cylinder Strength Mean? Concrete Construction

One of the most common misconceptions about the tested strength of a concrete cylinder is that it represents the strength of the concrete in place. While in a perfect world there might be a correlation between the two, what cylinder strength is intended to represent is the potential strength of the concrete as delivered—the highest strength

## Compressive Strength of Concrete Cylinders

The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compression-testing machine.
