Workability is usually measured because of the concrete slump check, an easy measure on the plasticity of the fresh batch of concrete following the ASTM C 143 or EN 12350-two test specifications. Slump is normally measured by filling an "Abrams cone" with a sample from a fresh new batch of concrete. The cone is placed With all the vast end down onto a degree, non-absorptive surface area. It can be then loaded in three levels of equal volume, with Just about every layer staying tamped which has a metal rod to consolidate the layer.
