混凝土.第1部分:规定的方法和规范制定者的指南

[中文适用范围]： ISO 22965 的本部分适用于现浇结构混凝土、预制结构混凝土以及建筑物和土木工程结构的结构预制产品。混凝土可以是现场混合的、预拌的或在预制混凝土产品工厂生产的。ISO 22965 的本部分适用于压实后除夹带空气外不留有明显滞留空气的混凝土以及普通混凝土、重质混凝土和轻质混凝土。针对特定产品（例如预制产品）或 ISO 22965 本部分范围内的工艺的其他国际标准可能要求或允许与 ISO 22965 的本部分有所偏差。ISO 22965 的本部分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导。资料性附件提供了有关规范的一般指导。与当地情况相关的更具体的规范指导可在国家附件中提供。 ISO 22965 的本部分不适用于 - 最大骨料尺寸等于或小于 4 毫米或 5 毫米的混凝土（砂浆）， - 加气混凝土， - 泡沫混凝土， - 具有开放结构的混凝土（“无细骨料”混凝土）， - 密度小于 800 kg/m3 的混凝土， - 耐火混凝土。 ISO 22965 的本部分不涵盖混凝土生产和交付过程中保护工人的健康和安全要求。 [外文原描述]： 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/m 3 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.
