Workability is บริษัทเอสเอชซี สหะชัยคอนกรีต จำกัด usually measured from the concrete slump test, a straightforward measure of the plasticity of a fresh batch of concrete next the ASTM C 143 or EN 12350-2 test expectations. Slump is Usually calculated by filling an "Abrams cone" with a sample from the refreshing batch of concrete. The cone is positioned with the wide conclude down on to a degree, non-absorptive area.
