Later it was proposed as “Self Compacting High-Performance Concrete”. It was named “High-Performance Concrete”. The usable version of self-compacting concrete was completed in 1988. Hajime Okamura (Father of SCC Technology). A committee was formed to study the properties of self-compacting concrete, including a fundamental investigation on the workability of concrete.
