1.1 本规程概述了硬化混凝土样品的岩相检查程序。所检查的样品可以取自混凝土结构，可以是混凝土产品或其部分，也可以是暴露在自然环境中、模拟使用条件下或经过实验室测试的混凝土或砂浆样品。短语“混凝土结构”旨在包括由水硬性水泥混凝土建造的各种物体、单元或结构。 1.2 本文概述的岩相程序适用于检查所有类型硬化混合物的样品，包括混凝土、砂浆、水泥浆、石膏、灰泥、水磨石等。 在本实践中，检验材料被指定为“混凝土”，即使评注可能适用于其他混合物，除非提及的是混凝土以外的介质。 1.3 硬化混凝土岩相检验的目的和程序见以下章节: 部分 岩学家的资质和技术人员的使用 4. 检查目的 5. 仪器 6. 仪器的选择和使用 7. 样品 8. 样品检查 9 试样制备 10 视觉和体视显微镜检查 11 偏光显微镜检查 12 粘贴要素 13 汇报 14 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。 每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 注1: 筛孔尺寸由规范中的标准名称确定 E11 . 括号中给出的替代名称仅供参考，并不代表不同的标准筛孔尺寸。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 具体危险说明见 6.2.10.1 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This practice outlines procedures for the petrographic examination of samples of hardened concrete. The samples examined may be taken from concrete constructions, they may be concrete products or portions thereof, or they may be concrete or mortar specimens that have been exposed in natural environments, or to simulated service conditions, or subjected to laboratory tests. The phrase “concrete constructions” is intended to include all sorts of objects, units, or structures that have been built of hydraulic cement concrete. 1.2 The petrographic procedures outlined herein are applicable to the examination of samples of all types of hardened mixtures, including concrete, mortar, grout, plaster, stucco, terrazzo, and the like. In this practice, the material for examination is designated as “concrete,” even though the commentary may be applicable to the other mixtures, unless the reference is specifically to media other than concrete. 1.3 The purposes of and procedures for petrographic examination of hardened concrete are given in the following sections: Section Qualifications of Petrographers and Use of Technicians 4 Purposes of Examination 5 Apparatus 6 Selection and Use of Apparatus 7 Samples 8 Examination of Samples 9 Specimen Preparation 10 Visual and Stereomicroscope Examination 11 Polarizing Microscope Examination 12 Paste Features 13 Report 14 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. Note 1: Sieve size is identified by its standard designation in Specification E11 . The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in 6.2.10.1 . 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.
