Self-compacting concrete (SCC)
Self-compacting concrete (SCC) is a flowing concrete that does not require vibration and, indeed, should not be vibrated. It uses superplasticisers and stabilisers to significantly increase the ease and rate of flow. It achieves compaction into every part of the mould or formwork simply by means of its own weight without any segregation of the coarse aggregate.
The consistence of the concrete is specified and measured as a flow rate rather than the normal slump test.
- Health and safety benefits (as no vibration is required).
- Faster construction times.
- Increased workability and ease of flow around heavy reinforcement.
- Excellent durability.
Having no need for vibrating equipment spares workers from exposure to vibration. No vibration equipment also means quieter construction sites.
