Several test procedures have been successfully employed to measure the plastic properties of Self-Consolidating Concrete.

The slump flow test, using the traditional slump cone, is the most common field test and is in the process of being standardized by ASTM.

5.3 It is difficult to produce self-consolidating concrete that is both flowable and nonsegregating using coarse aggregates larger than 25 mm [1 in.].

Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in.] in size.
