Self-consolidating concrete Wikipedia
Self-consolidating concrete or self-compacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets). In everyday terms, when poured, SCC is an extremely fluid mix with the following distinctive practical fe
Self-Compacting Concrete: Materials, Properties, and
Self-compacting concrete (SCC) is design to achieve three functional requirements, which are filling ability, passing ability, and resistance to segregation. These requirements are necessary to properly fill the formwork and adequately encapsulate reinforcing bars only through the action of gravity, while maintaining good homogeneity.

Difference between Self Compacting and Normal Concrete
21.09.2018· The Self-compacting concrete makes use of viscosity modifying agents (VMA) which creates problems when used in normal concrete. The VMA are pseudo polymers that helps in the reduction of aggregate segregation when compared to NCC. Other than the VMA agent, the viscosity of SCC is high as it has a low water to powder ratio compared to NCC.
