ASTM Test Methods for Self-Consolidating Concrete
The flow rate is influenced by the concrete’s viscosity. These notes and footnotes excluding those in tables and figures shall not be considered as aastm of the standard. Historical Version s – view previous versions of standard. 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.
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. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. The slump flow test can be used in production to assess the consistency of SCC. A difference less than 25 mm [1 in. This standard does not purport to address all of the safety concerns, if any, associated with its use. If the document is revised or amended, you will be notified by email.
Combining values from the two systems may result in nonconformance with the standard. 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. The following ASTM standard test methods have been developed to address these fresh concrete properties.
This test method is applicable for laboratory use in comparing the passing ability of different concrete mixtures. The test method is limited to concrete with nominal maximum size of aggregate of 1 in [25 mm]. A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability.

Subscription pricing is determined by: A difference of less than 1 in. The test method is limited to concrete with nominal maximum size of aggregate of 1 in [25 mm]. Work Item s – proposed revisions of this standard. 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 shown in brackets. The stability can be observed by visually examining the concrete patty for evidence of segregation. BASF Construction Chemicals In the test method, a sample of freshly mixed concrete is placed in a cylindrical mold without tamping or vibration. The J-Ring is placed outside the slump cone so that the concrete flows through the legs of the ring when the cone is lifted.
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.
We have no amendments or corrections for this standard. As the voice of the U.
The orientation of the c16211 for the J-Ring test and for the slump flow test without the J-Ring shall be the same. C162 standard is not included in any packages. The slump flow with and without the J-Ring is measured.
The mold is lifted and the concrete allowed to spread. Warning— Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. Add to Alert PDF. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The slump cone can be either used the same way up or inverted.
