Once the cone is very carefully lifted off, the enclosed substance slumps a particular sum, owing to gravity. A relatively dry sample slumps very little, possessing a slump worth of 1 or 2 inches (twenty five or fifty mm) out of one foot (305 mm). A comparatively wet concrete sample may well slump as much as eight inches. Workability can be measured by the flow table test.

It even now may very well be lawfully necessary by local building codes, but it is not a need detailed within the Worldwide Residential Code, which serves as the model for most regional and point out codes.
