Self-compacting concrete was first developed in japan 1980’s .This concrete can flow through congested reinforcing bars with elimination of compaction. It enhances construction productivity, reduces overall cost and improves work environment. It helps in achieving better surface finish and improves workability. The admixtures such as super plasticizer and fly ash reduce heat of hydration. SCC is obtained by limiting the water/cement ratio incorporating an effective superplasticizer, high quality of fines increasing the sand / aggregate ratio.SCC is a material with good flow ability passing ability and resistance against seggregation.SCC is used in precast concrete construction due to its precast concrete construction due to its strength and filling ability. It improves construction of others engineering structures.
