Study on the development of medium strength self-compacting concrete using fly ash

Self-compacting concrete (SCC) is currently the trend setting construction material. Fresh self-compacting concrete flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, without any segregation and blocking. An extensive laboratory investigation has shown that self-compacting concrete can be made with the available Indian materials. This investigation aims to develop medium strength SCC incorporating Indian fly ash. Limits to the proportion of materials for satisfactory self-compacting properties have been defined. Both polycarboxilic based superplasticiser and viscosity-modifying agent have been incorporated. Some durability study has been also performed.
