This European Standard applies to SCC for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures. This European Standard applies to SCC which is self-compacting by gravity to retain no appreciable amount of entrapped air other than entrained air. This Standard applies to normal-weight concrete. Experience with SCC containing light-weight or heavy-weight aggregate and fibres is limited. Some but not all provisions of this Standard will apply for these forms of SCC but the requirements have to be determined on a case by case basis. The SCC may be mixed on site, ready-mixed concrete or produced in a plant for precast concrete products.
