Self consolidating concrete slump
The test method is a laboratory procedure to determine the potential static segregation.
An SCC mixture is generally considered to be acceptable if the percent segregation is less than 10% (ACI 237R-07).
The slump cone is placed in the center of the base and a sample of concrete is poured into the slump cone without rodding or other consolidation.

The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures.
A common range of slump flow for SCC is 18 to 30 in. The slump flow test can be used in production to assess the consistency of SCC.
It is defined as a concrete mix that can be placed purely by means of its own weight, with little or no vibration.
