What is Self Compacting Concrete?

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. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete.

Self-compacting concrete has higher fines content than conventional concrete due to higher binder content and a different combined aggregate grading curve. These adjustments, combined with specially adapted superplasticisers, produce unique fluidity and inherent compactability.

Potential of Using Sika ViscoFlow® technology for Self Compacting Concrete
  • Excellent self-compacting properties
  • Significant water reductions
  • Easy and simplified placing
  • Excellent flow even around dense reinforcement
  • Easy finishing
  • High strength
  • Consistent slump and flow
