Definition of self-consolidating concrete (SCC)

Self-consolidating concrete (SCC) is highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. In general, SCC is concrete made with conventional concrete materials and, in some cases, with a viscosity-modifying admixture (VMA). SCC has also been described as self-compacting concrete, self-placing concrete, and self-leveling concrete, which all are subsets of SCC. The nomenclature of this technology has been previously discussed (Szecsy 2002). In this report, conventional concrete is referred to as concrete that does not meet the definition of SCC.
