(Test Method)Standard Test Method for Slump Flow of Self-Consolidating Concrete
Standard Test Method for Slump Flow of Self-Consolidating Concrete
SIGNIFICANCE AND USE
This test method provides a procedure to determine the slump flow of self-consolidating concrete in the laboratory or the field.
This test method is used to monitor the consistency of fresh, unhardened self-consolidating concrete and its unconfined flow potential.
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. Appendix X1 provides non-mandatory visual rating criteria that may be used to classify the ability of a self-consolidating concrete mixture to resist segregation (stability).
The rate at which the concrete spreads is related to its viscosity. Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures.
SCOPE
1.1 This test method covers the determination of slump flow of self-consolidating concrete.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, 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. (WARNING—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. )

4. Summary of Test Method
4.1 Asample of freshly mixed concrete is placed in a mold shaped aseither in the frustum of a cone.upright or inverted position.
The concrete is placed in one lift without tamping or vibration. The mold is raised, and the concrete is allowed to spread. After
spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions, and slumpdirections.
Slump flow is the average of the two diameters.
