This standard does not purport to address all of the safety concerns, if any, associated with its use. After spreading ceases, two orthogonal diameters of the concrete patty are measured. This standard does not purport to address all of the safety concerns, if any, associated with its use.

ELE International – J-Ring

The test method is limited to concrete with nominal maximum size of aggregate of 1 in [25 mm].

Link to Active This link will always route to the current Active version of the standard. The test method is a laboratory procedure to determine the potential static segregation.

The slump flow with and without the J-Ring is measured. This standard is not included in any packages. After 15 minutes, the mold is separated into three sections representing the top, middle, and bottom of the cylinder.

A difference of less than 1 in. This test method is applicable for laboratory use in comparing the passing ability of different concrete mixtures.

It is also applicable in the field as a quality control test. The stability can be observed by visually examining the concrete patty for evidence of segregation. 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. A difference less than 25 mm [1 in. The J-Ring is placed outside the slump cone so that the concrete flows through the legs of the ring when asm cone is lifted. Standards Subsctiption may be the perfect solution.

Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and asfm upon prolonged exposure. Combining values from the two systems may result in non-conformance with the standard.

The slump flow test can be used in production to assess the consistency of SCC. 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. Each section is removed individually and the concrete in the top and bottom sections washed adtm a No. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
