In late 1980’s and early 90’s research lead by Prof. H. Okamura of the University of Tokyo pioneered in the development of such mixes of concrete with high fluidity which they coined as Self Compacting Concrete (SCC)(Okamura 2003, Oguchi M, et. al. 1996). SCC can be described as a high performance material which flows under its own weight by completely filling of formworks even when access is hindered by narrow gaps between reinforcement bars. SCC can also be used in situations where it is difficult or impossible to use mechanical compaction for fresh concrete, such as underwater concreting, cast in-situ pile foundations, machine bases and columns or walls with
congested reinforcement.
