What is Self-Compacting Concrete (SCC)?

Self-Compacting Concrete (SCC) is a highly flowable concrete that spreads and compacts under its own weight without the need for vibration. It easily fills complex formwork and congested reinforcement while producing a smooth, high-quality finish.

Specifications

  • Concrete Type: Self-Compacting Concrete (SCC)
  • Compaction: No vibration required
  • Flowability: Excellent
  • Slump Flow: 650–800 mm (typical)
  • Segregation Resistance: High
  • Workability: Excellent
  • Surface Finish: Smooth and uniform

Key Features

  • Self-leveling and self-compacting
