Abstract— Self compacting concrete has been described as “the most revolutionary development in concrete construction for several decades”. A self compacting concrete, which has excellent deformability and resistance to segregation and can be filled in heavily reinforced form work without vibrators was developed 20 years ago. SCC is defined as a concrete, which can be placed and compacted into every corner of formwork, purely by means of its self-weight by eliminating the need of either external input from vibrators or any other type of effort. Due to its specific properties, SCC may contribute a significant improvement in the quality of concrete structures and open up new fields for the application of concrete.The use of self-compacting concrete is spreading world wide because of its very attractive properties in the fresh state as well as after hardening. SCC improves the quality, durability and reliability of concrete structures and eliminates some of the potential for human error. It will replace manual compaction of fresh concrete with a modern semi automatic placing technology and in that way improve health and safety on and around the construction site.As the main feature of SCC is the behavior in the fresh state, the mix design is especially focused in this point. SCC is designed to be able to flow under its own weight without external vibration and with sufficient viscosity. The flow behavior can be roughly evaluated by the slump flow test. For SCC we will need a high final spread and a maximum limit to the slumping time T 50cm. A concrete mix can only be classified as self compacting concrete if the requirements for all three characteristics i.e. filling ability, passing ability, segregation resistance, are fulfilled.Superpasticizers are an essential component of SCC to provide the necessary workability. Other types may be incorporated as necessary, such as viscosity modifying admixtures (VMA) for stability; air-entraining admixtures to improve freeze thaw resistance, retarders for control of setting etc. Fly ash is a fine inorganic material with pozzolanic properties, which can be added to SCC to improve its properties.
