Notice that the concrete has flowed like a viscous liquid rather than
exhibiting the traditional slump of a high slump concrete. It can be

admixtures that prevent segregation.
high-slump concretes have been plagued with the tendency
to bleed and segregate. The development of SCC makes it possible to
concrete that would fall under the category of high-slump concrete;
its behavior far exceeds that of a high-slump mix.
