Self-Consolidating Concrete (SCC) test measures the ability of the concrete mixture to flow under its own weight to completely fill all spaces within the formwork set. A modified slump cone is positioned inverted in the middle of the J-Ring and filled with concrete in a single lift. The cone is then lifted straight up and the diameter of the resulting circular flow of concrete is measured. A similar test is then run without the J-Ring in place and the difference in the flow diameters is recorded as the passing ability. Includes heavy duty steel J-Ring, metal slump cone, straight edge, and large HDPE plastic base plate with centering rings. Meets ASTM C-1621, C-1621M-06, EN-12350-12
