The slump cone can be either used the same way up or inverted. This test method is applicable for laboratory use in comparing the passing ability of different concrete mixtures.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. We have no amendments or corrections for this standard. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

BASF Construction Chemicals In the test method, a sample of freshly mixed concrete is placed in a cylindrical mold without tamping or vibration.

ELE International – J-Ring

The flow rate is influenced by the concrete’s viscosity. The J-Ring is placed outside the slump cone so that the concrete flows axtm the legs of the ring when the cone is lifted.

The test method is suitable for use in the laboratory and in the field. View directory of all issues.

A difference less than 25 mm [1 in. The slump flow with and without the J-Ring is measured. A difference greater than 2 in.

This standard c11621 not purport to address all of the safety concerns, if any, associated with its use. The stability can be observed by visually examining the concrete patty for evidence of segregation. Each section is removed individually and the concrete in the top and bottom sections washed over a No.

Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. 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. 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. The slump flow is the average of the two diameters. Within the text, the SI units are shown in brackets.
