(1) This European Standard applies to concrete for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures.<\/p>\n
(2) The concrete under this European Standard can be:<\/p>\n
normal-weight, heavy-weight and light-weight;<\/p>\n<\/li>\n
mixed on site, ready-mixed or produced in a plant for precast concrete products;<\/p>\n<\/li>\n
compacted or self-compacting to retain no appreciable amount of entrapped air other than entrained air.<\/p>\n<\/li>\n<\/ul>\n
(3) This standard specifies requirements for:<\/p>\n
the constituents of concrete;<\/p>\n<\/li>\n
the properties of fresh and hardened concrete and their verification;<\/p>\n<\/li>\n
the limitations for concrete composition;<\/p>\n<\/li>\n
the specification of concrete;<\/p>\n<\/li>\n
the delivery of fresh concrete;<\/p>\n<\/li>\n
the production control procedures;<\/p>\n<\/li>\n
the conformity criteria and evaluation of conformity.<\/p>\n<\/li>\n<\/ul>\n
(4) Other European Standards for specific products e.g. precast products or for processes within the field of the scope of this standard may require or permit deviations.<\/p>\n
(5) Additional or different requirements may be given for specific applications in other European Standards, for example:<\/p>\n
concrete to be used in roads and other trafficked areas (e.g. concrete pavements according to EN 13877\u20111<\/span> <\/span>);<\/p>\n<\/li>\n special technologies (e.g. sprayed concrete according to EN 14487<\/span> <\/span>).<\/p>\n<\/li>\n<\/ul>\n (6) Supplementing requirements or different testing procedures may be specified for specific types of concrete and applications, for example:<\/p>\n concrete for massive structures (e.g. dams);<\/p>\n<\/li>\n dry mixed concrete;<\/p>\n<\/li>\n concrete with a D<\/i> max<\/sub> of 4 mm or less (mortar);<\/p>\n<\/li>\n self-compacting concretes (SCC) containing lightweight or heavy-weight aggregates or fibres;<\/p>\n<\/li>\n concrete with open structure (e. g. pervious concrete for drainage).<\/p>\n<\/li>\n<\/ul>\n (7) This standard does not apply to:<\/p>\n aerated concrete;<\/p>\n<\/li>\n foamed concrete;<\/p>\n<\/li>\n concrete with density less than 800 kg\/m 3<\/sup>;<\/p>\n<\/li>\n refractory concrete.<\/p>\n<\/li>\n<\/ul>\n (8) This standard does not cover health and safety requirements for the protection of workers during production and delivery of concrete.<\/p>\n Concrete.
