This test method is applicable for laboratory use in comparing the passing ability of different concrete mixtures. Combining values from the two systems may result in nonconformance with the standard. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
The astk is lifted and the concrete allowed to spread. Please first log in with a verified email before subscribing to alerts. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.
ASTM Test Methods for Self-Consolidating Concrete
The stability can be observed by visually examining the concrete patty for evidence of segregation. Already Subscribed to this document. A difference less than 25 mm [1 in. Within the text, the SI units are shown in astk.
It is the responsibility of the user aetm this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
The orientation of the mold for the J-Ring test and for the slump flow test without the J-Ring shall be the same. Your Alert Profile lists the documents that will be monitored. The flow rate is influenced by the c16621 viscosity.

Please contact the Editor: This standard does not purport to address all of the safety concerns, if any, associated with its use. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Within the text, the SI units are awtm in brackets. Combining values from the two systems may result in non-conformance with the standard.
A common range of slump flow for SCC is 18 to 30 in.
This standard is also available to be included in Standards Subscriptions. These notes excluding those in tables and figures shall not be considered as requirements of the standard. Need more than one copy?
It is also applicable in the field as a quality control test. The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. A sample of freshly mixed concrete is placed in the cone in one lift without tamping or vibration. Active view current version of standard. Warning— Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
Work Item s – proposed revisions of this standard. The slump flow test can be used in production to assess the consistency of SCC.

Combining values from the two systems may result in nonconformance with the standard.

The test method is limited to concrete with nominal maximum size of aggregate of 1 in [25 mm]. A difference greater than 2 in. Subscription pricing is determined by: Add to Alert PDF.
After 15 minutes, the mold is separated into three sections representing the top, middle, and bottom of the cylinder. The retained aggregate from each section is weighed and the static segregation calculated as the difference between the bottom and top sections divided by the average weight.
These notes excluding those in tables and figures shall not be considered as requirements of the standard. Work Item s astj proposed revisions of this standard. After spreading ceases, two orthogonal diameters of the concrete patty are measured.
Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
The flow rate is determined by measuring the time it takes for the outer asrm of the concrete to reach a diameter of 20 in. Standards Subsctiption may be the perfect solution. Historical Version s – view previous versions of standard.
