The Slump Flow Test for High-Workability Concrete ...

Despite their inherent limitations, single-point workability tests continue to be used for the specification and quality control of concrete. The development of stable, high-workability mixes with a collapsed slump has led to the use of the flow test, more popular in Europe, and the slump flow test, used extensively in Asia.
