1. INTRODUCTION: Selfcompacting concrete refers to a special type of concrete that can be compacted to every corner of the formwork, purely by means of its own selfweight and without the need for vibrating or compaction. Scc is selfcompacting itself alone due to its own self weight and it is characterized by high segregation resistance.
