Modified Slump Cone for SCC Passing Ability Test
The Self Consolidating Concrete Slump helps to ensure the proper flow of concrete. Structural elements designed with 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 Self Consolidating Concrete 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.
Depending upon the procedure selected, a modified Self Consolidating Concrete slump cone is positioned either inverted or upright 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. Additional measurements or visual classifications may also be determined at the conclusion of the test. Be sure you have everything you need to test for proper construction and pick up your J ring concrete test and concrete thermometer at Certified MTP.
