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.

After spreading ceases, two orthogonal diameters of the concrete patty are measured. Subscription pricing is determined by: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Historical Version s – view previous versions of standard. A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability. The mold is lifted and the concrete allowed to spread.

After 15 minutes, the mold is separated into three sections representing the top, middle, and bottom of the cylinder.

View directory of all issues. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. 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. BASF Construction C16221 In the test method, a sample of freshly mixed concrete is placed in a cylindrical mold without tamping or vibration.

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. The slump cone can be c6121 used the same way up or inverted. Need more than one copy? The test method is suitable for use in the laboratory and in the field. This standard is also available to be included in Standards Subscriptions.

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

The following ASTM standard test methods have been developed to address these fresh concrete properties. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability asttm regulatory limitations prior to use. Work Item s – proposed revisions of this standard.

ASTM C1621

The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. The flow rate is influenced by the concrete’s viscosity. Link to Active This link will always route to the current Active version of the standard.

The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. A common range of slump flow for SCC is 18 to 30 in. The test method is a laboratory procedure to determine the potential static segregation.
