The test method is limited to concrete with nominal maximum size of aggregate of 1 in [25 mm]. Self-consolidating concrete SCC must have the ability to flow under its own weight, to pass reinforcing bars or other obstacles without segregation, and not segregate during or after casting. A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability.

Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
