BAS EN 206-9:2011

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. In addition to those in EN 206-1:2000, this European Standard specifies requirements for: - the constituent materials of SCC; - the properties of fresh and hardened SCC and their verification; - the limitations for SCC composition; - the specification of SCC; - the factory production control procedures; - the conformity criteria. Other European Standards for specific products e.g. precast products or for processes within the field of the scope of this European Standard may require or permit deviations from this European Standard. The limitations of scope in EN 206-1:2000 apply to SCC conforming to this European Standard. This European Standard does not cover health and safety requirements for the protection of workers during production and delivery of concrete.
