WebApr 1, 2024 · Self-consolidating concrete (SCC) is a specialized type of concrete, characterized by its high flowability and resistance to segregation. It was originated in Japan by Okamura in the late 1980s. • SCC is measured using the flow table test (slump-flow test) rather than the usual concrete slump test, as it is too fluid to keep its shape when the cone is removed. A typical SCC mix will have slump-flow of around 500 – 700 mm. • SCC is weakened, not strengthened, by vibration. As vibration is not needed for compacting the mix, all that it achieves is to separate and segregate it.
