Self-Compacting Concrete (SCC)

What is self-compacting concrete (SCC)?

Self-Compacting Concrete (SCC), also referred to as self-consolidating concrete, is a flowing concrete that doesn’t require external force or vibration for compaction, unlike traditional concrete. This means that no vibration equipment is needed, which allows for the avoidance of worker exposure to vibrations and reduces noise on construction sites. With SCC, achieving high-quality and long-lasting finishes becomes a straightforward and efficient process.

What materials is scc composed of?

  • Portland Cement: Portland cement is the primary binding agent in SCC, just as in traditional concrete.
  • Aggregates: While SCC utilizes similar properties with traditional concrete, including the use of cement, water and aggregates like sand and gravel, it distinguishes itself by typically incorporating finer aggregates.
  • Water: Water is added into the mix to achieve the desired consistency. The water-cement ratio is carefully controlled to ensure the right level of workability without excessive fluidity.
  •  Admixtures: Admixtures are chemical or mineral additives mixed into the concrete to improve its properties. They can enhance workability, reduce water content, accelerate or delay setting time and increase durability.
