This test method covers determination of the passing ability (Note 1) of self-consolidating
concrete (SCC) by the J-Ring method, both in the laboratory and in the field. SCC is defined as a
highly workable concrete that can flow through densely reinforced or complex structural elements
under its own weight without vibration and adequately fill voids without experiencing segregation
or excessive bleeding.
Note 1--Passing ability is defined as the ability of SCC to flow through openings such as the
spaces between reinforcing bars without segregation or without aggregate blocking. Blocking is
defined as the condition in which pieces of coarse aggregate combine to form elements large
enough to obstruct the flow of the SCC between reinforcing bars or other obstructions in the
concrete formwork.
The values stated in either SI units or inch-pound units are to be regarded separately as standard.
Within the text, the inch-pound units are shown in brackets. The values stated in each system are
not exact equivalents; therefore, each system shall be used independently of the other. Combining
values from the two systems may result in nonconformance with the standard.
