A difference of less than 1 in. Use of Fly Ash in Concrete. ACI has over 95 chaptersstudent chapters, and nearly 20, members spanning over countries.
The information in this document is expected to inform concrete producers, users, and specifiers of SCC of known practices acii processes. The J-Ring is self-consolidaating outside the slump cone so that the concrete flows through the legs of the ring when the cone is lifted. The test method is a laboratory procedure to determine the potential static segregation.

Please contact the Editor: Guide for Concrete Inspection. According to ACI R, the slump flow should not differ by more than 2 in.

The mold is lifted and the concrete allowed to spread. Remember me for one month. Manual of Concrete Practice-7 Volume Set.
After spreading ceases, two orthogonal diameters of the concrete patty are measured. The flow rate is determined by measuring the time it takes for the outer edge of the concrete to reach a diameter of 20 in. The slump cone can be either used the same way up or inverted.
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.

ASTM Test Methods for Self-Consolidating Concrete
The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. FORMAT Single User Subscription Site License Subscription BOOKS All Books PACKAGES All Packages EDITION to PUBLISHER.
The flow rate is influenced by the concrete’s viscosity. concreet
BASF Construction Chemicals In the test method, a sample of freshly mixed concrete is placed in a cylindrical mold without tamping or vibration. A nonmandatory appendix of ASTM C aic a procedure for a relative measurement of flow rate, viscosity, and stability. After 15 minutes, the mold is separated into three sections representing the top, middle, and bottom of the cylinder.

The following ASTM standard test methods have been developed to address these fresh concrete properties. Land Use and Development. Copyright Compu-tecture, Inc. Each section is removed individually and the concrete in the top and bottom sections washed over a No.
237R-07 Self-Consolidating Concrete
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.
Enter your account email address to request a password reset: The stability can be observed by visually examining the concrete patty for evidence of segregation.
The slump flow avi and without the J-Ring is measured. No items in cart.
