HDPE Strike-Off Bar for SCC J-Ring Test Set
Structural elements designed with congested reinforcing steel often require the use of Self-Consolidating Concrete (SCC) mix designs to assure structures free of voids and honeycombing. The J-Ring test, in conjunction with the Slump-Flow test, is one way to determine the passing ability of SCC, defined as the ability of the concrete to flow under its own weight to completely fill all spaces within the formwork. Can also be used for concrete cylinder mold or air meter vessel, slump cone or unit weight measure.
Based on the chosen procedure, a modified slump cone is placed either upright or inverted at the center of the J-Ring and filled with concrete in one go. The cone is then lifted vertically, and the diameter of the resulting concrete flow is measured. The test is repeated without the J-Ring, and the difference in flow diameters is recorded as the passing ability. Additional measurements or visual observations may also be noted at the end of the test.
