1.1 ASTM水硬性水泥砂浆和混凝土的试验方法和实践的大多数章节适用于聚合物改性剂制成的试样的制备和测试。然而，也有一些例外情况，尤其是固化，需要特殊程序才能开发聚合物改性的固有特性。这些测试方法涵盖了这些例外情况。 1.2对于测试聚合物改性砂浆和混凝土样本，本标准中的程序取代参考ASTM测试方法和实践中的程序。这些试验方法不适用于干燥的包装砂浆和混凝土。 1.3以国际单位制表示的数值应视为标准值。 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。 ====意义和用途====== 这些试验方法用于开发数据，以与规范C 1438的要求进行比较 . 标准化程序用于比较由聚合物改性混凝土或砂浆的试验混合物制成的试样的性能与由参考混合物制成的试样的性能。这些测试方法不是为了模拟工作条件。

1.1 Most sections of ASTM test methods and practices for hydraulic cement mortar and concrete apply to the preparation and testing of specimens made with polymer-modifiers. However, there are some exceptions, most notably curing, that need special procedures in order to develop the properties inherent with polymer-modification. These test methods cover these exceptions. 1.2 For testing polymer-modified mortar and concrete specimens, the procedures in this standard supersede those in the referenced ASTM test methods and practices. These test methods are not applicable to dry, packaged mortar and concrete. 1.3 The values stated in SI units are to be regarded as standard. 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. ====== Significance And Use ====== These test methods are used to develop data for comparison with the requirements of Specification C 1438 . Standardized procedures are used to compare the properties of specimens made from test mixtures of polymer-modified concrete or mortar with the properties of specimens made from reference mixtures. These test methods are not intended to simulate job conditions.
