V Funnel is one of the apparatus of the SCC (Self Consolidating Concrete) test accessories. These tests are used to determine the flowability and passing ability of Self Consolidating Concrete (SCC) as defined in ASTM C1621. Passing ability refers to the ability of SCC, under its own weight (without vibration), to flow into and completely fill the spaces within an intricate framework, containing obstacles such as reinforcement bars.
