SCC is defined as “concrete that is able to flow and consolidate under its own weight, completely fill the formwork even in the presence of dense reinforcement, whilst maintaining homogeneity and without the need for additional compaction”.

Self-compacting concrete (SCC) was first developed in Japan (in the mid to late 1980s ) as a means to create uniformity in the quality of concrete by controlling the ever present problem of insufficient compaction by a workforce that was losing skilled labour and by the increased complexity of designs and reinforcement details in modern structural members. Durability was the main concern and the purpose was to develop a concrete mix that would reduce or eliminate the need for vibration to achieve consolidation. 

Self-compacting concrete achieves this by its unique fresh state properties. In the plastic state, it flows under its own weight and maintain homogeneity while completely filling any formwork and passing around congested reinforcement. In the hardened state, it equals or excels standard concrete with respect to strength and durability.

The use of SCC concrete has been increasing in the United States also during the last 5 years. Currently the technology is being primarily applied to the precast industry. Other segments being targeted are flatwork, columns and wall construction. The applications of SCC are many, limited only by the industry's knowledge of it, ability to produce it and acceptance of it.

The usual self-compacting concretes have compressive strengths in the range of 60-100N/mm². However Ultra High Performance Self-Compacting Concrete (UHPSCC) with a strength about 150 N/mm² have also been successfully developed.
