1.1 本规范涵盖了粉末状彩色和白色颜料作为混凝土掺合料的基本要求，用于生产整体彩色混凝土。如果颜料是多组分混合物的成分，则本规范适用于混合物的颜料成分。本规范不旨在确定颜料与任何其他混凝土外加剂的相容性，除非它们按照以下要求进行组合测试 4.7 . 1.2 本规范不包括在高温下使用低- 压力（大气压）或高压（高压釜）蒸汽用于加速固化过程。 1.3 除了定义颜料本身的测试外，还包括有限数量的混凝土测试，以确定对凝结时间、空气含量和抗压强度的影响。如果特定工作需要更广泛的信息，卖方和用户应就额外的测试标准和程序达成一致。 1.4 颜料的最大规定剂量率，根据 4.7 ，应等于或小于水泥的10质量%。 当使用颜料组合来产生所需的颜色和颜色强度时，所有颜料组合的总剂量率不得超过组分颜料的任何单个最大剂量率。 1.5 以国际单位制或英寸-磅单位表示的值应单独视为标准值。每个系统中所述的值可能不是完全等效的；因此，每个系统都应独立使用。将两个系统的值结合起来可能会导致不符合标准。有些值只有国际单位制，因为英寸- 在实践中不使用磅当量。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the basic requirement for colored and white pigments in powder form to be used as admixtures in concrete for the purpose of producing integrally colored concrete. Where the pigments are a constituent of a multicomponent admixture, this specification applies to the pigment constituent of the admixture. This specification is not intended to establish compatibility of pigments with any other concrete admixtures unless they are tested in combination in accordance with 4.7 . 1.2 This specification does not include the determination of pigment stability when elevated temperature using low-pressure (atmospheric) or high-pressure (autoclave) steam is used to accelerate the curing process. 1.3 In addition to tests defining the pigments themselves, a limited number of tests on concrete are included to define the effects on setting times, air content, and compressive strength. If more extensive information is required for a particular job, additional testing criteria and procedures should be agreed upon between the seller and user. 1.4 The maximum prescribed dosage rate of a pigment, established in accordance with 4.7 , shall be equal to or less than 10 mass % of cement. When a combination of pigments is used to produce the desired color and color intensity, the total dosage rate of all pigments combined shall not exceed any of the individual maximum dosage rates of the component pigments. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Some values have only SI units because inch-pound equivalents are not used in practice. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
