It is also applicable in the field as a quality control test. View directory of all issues. The stability can be observed by visually examining the concrete patty for evidence of segregation. The flow rate is determined by measuring the time it takes for the outer edge of the concrete to reach a diameter of 20 in. Add to Alert PDF. If the document is revised or amended, you will be notified by email. These notes excluding those in tables and figures shall not be considered as ast, of the standard.
A difference of less than 1 in. The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

Subscription pricing is determined by: Combining values from the two systems may result in non-conformance with the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability. Within the text, the SI units are shown in brackets.
ELE International – J-Ring
The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. 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 difference greater c1261 2 in.
Warning— Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. The flow rate is influenced by the concrete’s viscosity. Please first log in with a verified email before atsm to alerts.
Combining values from the two systems may result in nonconformance with the standard. 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.
The test method is limited to concrete with nominal maximum size of aggregate of 1 in [25 mm]. Combining values from the two systems may result in nonconformance with the standard. Within the text, the SI units are shown in satm. You may delete a document from your Alert Profile at any time. Work Item s – proposed revisions of this standard. It is the responsibility of c162 user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to c161.
A sample of freshly mixed concrete is placed in the cone in one lift without tamping or vibration. We have no amendments or corrections for this standard. The test method is suitable for use in the laboratory and in the field. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the Author s and do not necessarily reflect the view of the Federal Highway Administration.
This test method is applicable for laboratory use in comparing the passing ability adtm different concrete mixtures. After spreading ceases, two orthogonal diameters of the concrete patty are measured. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Please contact the Editor: A common range of slump flow for SCC is 18 to 30 in.

Referenced Documents purchase separately The documents listed below are referenced within the asm standard but are not provided as part of the standard. The test method is a laboratory procedure to determine the potential static segregation. This standard does not purport to address all of the safety concerns, f1621 any, associated with its use. A difference less than 25 mm [1 in.
Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
