(1) In 1997, a RILEM committee (TC 174) on SCC was founded.

Today, SCC is studied worldwide with papers presented in almost every concrete-related conference.

SCC has also been described as self-compacting concrete, self-placing concrete, and self-leveling concrete, which all are subsets of SCC.

The need for this technology has grown as designers specify more heavily reinforced concrete members and ever more complex formwork.

Examples of applications are buildings and transportation structures like bridges and highway sound/barrier walls.Self-consolidating concrete (SCC) or self-compacting concrete, as it’s sometimes known, arrived as a revolution in the field of concrete technology.The concept was proposed by Professor Hajime Okamura of Kochi University of Technology, Japan, in 1986 as a solution to the growing durability concerns of the Japanese government.By 1988, the concept was developed and ready for the first real-scale tests.The first paper on SCC was presented at the second East-Asia and Pacific Conference on Structural Engineering and Construction (EASEC-2) in 1989, followed by another presentation at an Energy Diversification Research Laboratories (CANMET)/American Concrete Institute (ACI) meeting in 1992.

During his research, Okamura found that the main cause of the poor durability performances of Japanese concrete in structures was the inadequate consolidation of the concrete in the casting operations.
