Concrete cylinder compressive strength

Determines the compressive strength of a cylindrical concrete specimen.

Plain-language explanation

What the test tells you.

The project specification controls the exact method and acceptance requirement.

The ends of a cured cylinder are prepared as required, centred in a compression machine and loaded to failure.

Cured concrete cylinder, end-preparation or capping system, dimensional tools and calibrated compression machine.

Compressive strength from maximum load and the specimen’s cross-sectional area.

Provides a standard strength result for mixture qualification, quality control or comparison with the project specification.
