Manual of Concrete Practice Part 2 A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability.
R Self-Consolidating Concrete
The flow rate is influenced by the concrete’s seld-consolidating. Use of Fly Ash in Concrete. 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.
The information in this document is expected to inform concrete producers, users, and specifiers of SCC of known practices and processes. A difference of less than 1 in. According to ACI R, the slump flow should not differ by more than 2 in.
A sample of freshly mixed concrete is placed in the cone in one lift without tamping or vibration. The slump cone can be either used the same way up or inverted.

The test method is suitable for use in the laboratory and in the field. Remember me for one month.
ASTM Test Methods for Self-Consolidating Concrete
Each section is removed individually and the concrete in the top and bottom sections washed over a No. After spreading ceases, two orthogonal diameters of the concrete patty are measured.

ACI has over 95 chaptersstudent chapters, and nearly 20, members spanning over countries. Please contact the Editor: Are you sure you want to empty the cart? No selt-consolidating in cart.
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. Enter your personal account email address to request a password reset: Please login to your authorized staff account to use this feature.
The slump flow test can be self-consolodating in production to assess the consistency of SCC.
A difference greater than 2 in. If you like to setup a quick demo, let us know at support madcad. This book also exists in the following packages This report contains the current state of knowledge with respect to SCC. The test method is a laboratory procedure to determine the potential static segregation.

The following ASTM standard test methods have been developed to address these fresh concrete properties. 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.
