Workability is usually calculated with the concrete slump exam, an easy measure on the plasticity of a new batch of concrete following the ASTM C 143 or EN 12350-two examination specifications. Slump is Generally measured by filling an "Abrams cone" with a sample from the clean batch of concrete. The cone is placed with the large close down onto a amount, non-absorptive area.
