1.1 本试验方法规定了通过等温传导量热法测定水硬性胶凝材料在试验龄期长达7天时的总水化热的装置和程序。 1.2 该测试方法还输出水合热速率与时间的关系数据，该数据可用于实践中涉及的其他分析目的 C1679 . 1.3 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.5 本国际标准是根据《关于制定国际标准的原则的决定》中确立的国际公认的标准化原则制定的世界贸易组织技术性贸易壁垒（TBT）委员会发布的ide和建议。 ======意义和用途====== 5.1 该方法适用于测定7天龄期内恒温水硬性水泥的总水化热，以确认符合规范要求。 5.2 这种方法是对实践的补充 C1679 通过提供热量计设备、校准和操作的详细信息。实践 C1679 强调通过分析热流的时间相关模式来解释水泥水化中的重要事件，但没有提供必要的详细程度，以在符合规范要求的特定测试年龄下给出精确测试结果。

1.1 This test method specifies the apparatus and procedure for determining total heat of hydration of hydraulic cementitious materials at test ages up to 7 days by isothermal conduction calorimetry. 1.2 This test method also outputs data on rate of heat of hydration versus time that is useful for other analytical purposes, as covered in Practice C1679 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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, 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 ====== 5.1 This method is suitable for determining the total heat of hydration of hydraulic cement at constant temperature at ages up to 7 days to confirm specification compliance. 5.2 This method compliments Practice C1679 by providing details of calorimeter equipment, calibration, and operation. Practice C1679 emphasizes interpretation significant events in cement hydration by analysis of time dependent patterns of heat flow, but does not provide the level of detail necessary to give precision test results at specific test ages required for specification compliance.
