The retained self-consolidatinh from each section is weighed and the static segregation calculated as the difference between the bottom and top sections divided by the average weight.
Click here to download full list of books. The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. Each section is removed individually and the concrete in the top and bottom sections washed over a No. The flow rate is influenced by the seof-consolidating viscosity.

Enter your account email address to request a password reset: 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. A common range of slump flow for SCC is 18 to 30 in.
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. A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability.
After spreading ceases, two orthogonal diameters of the concrete patty are measured.
