The British Standards institute (BSI) has revised ‘BS EN 206 Concrete – Specification, performance, production and conformity’.
The European Standard applies to concrete for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures. It covers all types of concrete and nearly all types of precast concrete. BS EN 206 also covers concrete for pavements where there are additional complementary requirements cited in the European Standard for Concrete pavements.
The revision specifically addresses that concrete may be designed for a working life of up to and over 100 years. This ensures that when its sustainability credentials are compared to other building materials the comparison may be carried out on an equitable basis.
BS EN 206 covers:
- Constituents of concrete
- Properties of fresh and hardened concrete and their verification
- Limitations for concrete composition
- Specification of concrete
- Delivery of fresh concrete
- Production control procedures
- Conformity criteria and evaluation of conformity.
The standard will be of use to members of a construction project who provide or require information on ready-mix concrete, including construction contractors, specialists, manufacturers, specifiers and structural engineers.
The amendment to BS 206 was a result of BSI’s participation in the CEN technical committee CEN/TC 104. BS EN 206 does not cover health and safety requirements for the protection of workers during production and delivery of concrete.
