concrete is dense, homogeneous and has at least engineering properties at par with and durability as traditional vibrated concrete. The principle behind Self Compacting Concrete (SCC) is that the settlement of aggregates is related to the viscosity of the fresh concrete. SCC can be produced using the same ingredients as that of normal concrete.

Shrinkage of self-compacting concrete. A comparative ...

Self-compacting concrete (SCC) is a concrete type that does not require vibration for placing and compacting. SCC possesses special technical features and properties that recommend its application in many jobs. Nevertheless, in some situations, it has been observed an inadequate behaviour of the material at early ages due to shrinkage.
