1.1 本标准实施规程规定了一套用于制备土工合成水泥基复合材料垫（GCCM）样品以进行指数性能测试的说明。 1.2 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可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 所有观察值和计算值应符合实践中确定的有效数字和舍入准则 D6026 . 1.3.1 为了将测量值或计算值与规定限值进行比较，测量值或计算值应四舍五入至规定限值中最接近的小数或有效数字。 1.3.2 本规程中用于规定如何收集/记录或计算数据的程序被视为行业标准。 此外，它们代表了通常应测量的有效数字。使用的程序不考虑材料变化、获取数据的目的、特殊目的研究或用户目标的任何考虑因素；通常情况下，增加或减少报告数据的有效位数以与这些考虑因素相称。考虑工程设计分析方法中使用的有效数字超出了本实践的范围。 1.4 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和健康实践，并确定监管限制的适用性。 第节给出了一些具体的危害说明 7. 关于危险。 ====意义和用途====== 5.1 本规程旨在创建适用于测定指数特性的试验的GCCM产品样本。 固化（硬化）样品不一定代表GCCM产品的现场应用，但可以代表已知类型产品的正确加水量，并为一致和可重复的指数性能测试提供基础。

1.1 This standard practice specifies a set of instructions for preparing samples of geosynthetic cementitious composite mat (GCCM) for index property testing. 1.2 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. 1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 . 1.3.1 For purposes of comparing measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal or significant digits in the specified limits. 1.3.2 The procedures used to specify how data are collected/recorded or calculated in this practice are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be measured. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the users objectives; and it is common practice to increase or reduce the significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this practice to consider significant digits used in the analytical methods for engineering design. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 7 on Hazards. ====== Significance And Use ====== 5.1 This practice is intended to create specimens of GCCM products appropriate for testing for the determination of index properties. Cured (hardened) samples are not necessarily intended to represent a field application of GCCM products but would be representative of the correct amount of water applied to a known style of product and provide a basis for consistent and repeatable index property testing.
