1.1 该测试方法的目的是确定GCCM材料的剥离强度，包括这些多层材料所具有的各种层。作为该方法的一部分，对未固化和固化/水合材料进行测试。 1.2 作为一种指数测试，这种方法将相对较少使用，并用于测试大量材料。本测试不适用于GCCM的常规质量控制测试。 1.3 以国际单位制为单位的数值应视为标准。括号中的值以英寸-磅为单位，以供参考。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者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。 1.5 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。 ====意义和用途====== 4.1 本试验方法适用于测试处于固化和未固化状态的GCCM材料。 这决定了这些多层材料的各个层的剥离强度，以确定临界界面强度。它与恒定拉伸速率型拉伸试验机配套使用。 4.2 剥离强度提供了由于存在于顶层和底层之间的任何连接元件（例如连接纤维/纱线或其他连接元件）而导致的顶层和底层间的连接强度的测量，或者提供了附着于顶层或底层的附加功能层之间的连接强度，这些附加功能层是GCCM用作复合物所必需的。特别地: 4.2.1 安装GCCM时，未固化剥离强度很重要，因为顶层和底层必须牢固连接，以便在将GCCM拖动/张紧到位时约束胶结材料。如果在处理过程中顶层/底层分离，胶凝材料不再受到约束，可能会过度水合，或者可能从GCCM中脱落或冲刷出来，导致固化复合材料的机械性能较差。 4.2.2 固化剥离强度在已安装的GCCM中很重要，因为如果顶层附着不充分，它可能会因水力剪切或风荷载而分离，或者完全分离并被冲洗到下游，从而造成堵塞和环境破坏。 如果附加功能层与顶部/底部/其他附加功能层连接不良，则这些层可能不再充当复合材料，这可能导致耐久性问题和多种潜在的失效模式。

1.1 The purpose of this test method is to determine the peel strength of GCCM materials to include the various layers these multilayer materials possess. Both uncured and cured/hydrated materials are tested as a part of this method. 1.2 As an index test, this method will be used relatively infrequently and to test large lots of material. This test is not intended for routine quality control testing of GCCMs. 1.3 The values in SI units are to be regarded as the standard. Values in inch-pound units are in parentheses for information. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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. ====== Significance And Use ====== 4.1 This test method is applicable for testing GCCM materials in both a cured and uncured state. This determines the peel strength of various layers of these multilayer materials to determine critical interface strength. It is used with a constant rate of extension type of tensile testing machine. 4.2 The peel strength provides a measure of the strength of the connection between the top and bottom layers due to any linking elements present between them (such as connecting fibers/yarns or other linking elements), or the strength of the connection between the additional functional layers attached to the top or bottom layer that are necessary for the GCCM to function as a composite. In particular: 4.2.1 Uncured peel strength is important when installing a GCCM because the top and bottom layers must be securely connected in order to constrain the cementitious material when dragging/tensioning the GCCM into position. If the top/bottom layers become detached during handling, the cementitious material is no longer constrained and may overhydrate or can potentially fall or wash out from the GCCM, causing the set composite to have poor mechanical properties. 4.2.2 Cured peel strength is important in an installed GCCM because if the top layer is insufficiently attached it may become detached due to hydraulic shear or wind loads, or become completely detached and washed downstream, causing blockages and environmental damage. If the additional functional layers are poorly attached to the top/bottom/other additional functional layers, the layers may no longer act as a composite, which could lead to durability issues and multiple potential failure modes.
