The compression test shows the best possible strength concrete can achieve in perfect conditions. The compression test measures concrete strength in the hardened state. Field concrete samples are prepared, cured and tested according to ASTM standard procedures. Specimens are prepared from concrete taken from different construction sites.

The compressive strength of concrete cube specimens is found out by uni-axially compressing them in a UTM. Ideally, in uni-axial compression there is no lateral restraint, but, lateral restraint develops due to the friction between the end faces of the concrete specimen & the platens of the testing machine.
