Self-Consolidating Concrete (SCC) was first developed in Japan almost 15 years ago, and it was not until the late 1990's that the U.
Self-consolidating concrete (SCC) is highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation.
In general, SCC is concrete made with conventional concrete materials and, in some cases, with a viscosity-modifying admixture (VMA).

The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces, and of ductile high-strength steel when subject to tension forces.
