Self-Compacting Concrete - Robustness of SCC

Abstract

Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. In the sense of SCC the robustness can be defined as the property that resist the changes of SCC like segregation during and placement (dynamic stability) and post placement (static stability). In a broader and more practical sense robustness as the ability of a given mixture to maintain its fresh properties and uniformity during processing, casting.
