self compacting concrete | PPT
2. By the early 1990's, Japan has developed and used SCC. Self compacted concrete is highly engineered concrete with much higher fluidity without segregation and is capable of filling every corner of formwork under its self weight . Thus SCC eliminates the vibration for the compaction of concrete without affecting its engineering properties. As of the …
