ISO 22965-1:2007适用于现浇结构的混凝土、预制结构以及建筑和土木工程结构的结构预制产品。混凝土可在现场搅拌、预拌混凝土或在工厂生产预制混凝土产品。
ISO 22965-1:2007适用于压实的混凝土,以保留除夹带空气以外的任何明显夹带空气,以及正常重量、重质和轻质混凝土。
特定产品的其他国际标准,例如预制产品,或ISO 22965-1:2007范围内的工艺,可能要求或允许偏离ISO 22965-1:2007。
ISO 22965-1:2007包含混凝土规范的要求以及规范制定者和供应商之间信息交换的指南。
资料性附录给出了规范的一般指南。关于与当地条件相关的规范,可在国家附录中给出更具体的指南。
ISO 22965-1:2007不适用于最大骨料粒径等于或小于4mm或5mm(砂浆)的混凝土、加气混凝土、泡沫混凝土、开放式结构混凝土(“无细骨料”混凝土)、密度小于800kg/m的混凝土和耐火混凝土。
ISO 22965-1:2007未涵盖混凝土生产和交付期间保护工人的健康和安全要求。
ISO 22965-1:2007 applies to concrete for structures cast in situ, pre-cast structures and structural pre-cast products for buildings and civil engineering structures. The concrete can be mixed on site, ready-mixed concrete or produced in a plant for pre-cast concrete products.
ISO 22965-1:2007 applies to concrete compacted to retain no appreciable amount of entrapped air other than entrained air and to normal-weight, heavy-weight and light-weight concrete.
Other International Standards for specific products, e.g. pre-cast products, or for processes within the field of the scope of ISO 22965-1:2007, can require or permit deviations from ISO 22965-1:2007.
ISO 22965-1:2007 contains requirements for the specification of concrete and guidance for the exchange of information between the specifier and supplier. An informative annex gives general guidance on specification. More specific guidance on specification related to the local conditions can be given in a national annex.
ISO 22965-1:2007 does not apply to concrete with a maximum aggregate size equal to or less than 4 mm or 5 mm (mortar), aerated concrete, foamed concrete, concrete with an open structure ("no-fine aggregate" concrete), concrete with a density less than 800 kg/m3 and refractory concrete.
ISO 22965-1:2007 does not cover health and safety requirements for the protection of workers during production and delivery of concrete.
