Phạm vi áp dụng / Scope of standard

This test method covers determination of the visual stability
index of self-consolidating concrete (SCC), 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.

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.

This standard does not purport to address all of the safety
concerns associated with its use. It is the responsibility of the
user of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations
prior to use.
