Modern structural elements are often designed with congested networks of reinforcing steel, requiring the high-flow characteristics of Self-Consolidating Concrete (SCC) to prevent voids and honeycombing. The ASTM C1621 J-Ring test, together with the C1611 Slump-Flow test, 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.
All products in this SCC group meet ASTM standards, with the exception of the L-Box for which an ASTM procedure is still pending.
