The slump cone can be either used the same way up or inverted. 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. 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.

If the document is revised or amended, you will be notified by email. A difference less than 25 mm [1 in. 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.

The stability can be observed by visually examining the concrete patty for evidence of segregation. F1621 standard is also available to be included in Standards Subscriptions.

The test method is suitable awtm use in the laboratory and in the field. Already Subscribed to this document. Combining values from the two systems may result in nonconformance with the standard. A sample of freshly mixed concrete is placed in the cone in one lift without tamping or vibration.

ELE International – J-Ring

The values stated in each system may not asm exact equivalents; therefore, each system shall be used independently of the other. A difference of less than 1 in. The slump flow with and without the J-Ring is measured.

The orientation of the mold for the J-Ring test and for the slump flow test without the J-Ring shall be the same.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. 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.
