聚合物水泥防水砂浆收缩率的不确定度评定
|
摘要
按照行业标准JC/T 984—2011《聚合物水泥防水砂浆》,采用比长仪测试防水砂浆的收缩率。依据JJF 1059.1—2012《测量不确定度评定与表示》分析了各种不确定度的来源,并对不确定度进行评估,试验结果表明,防水砂浆的收缩率测试结果为(2.376±0.1661)×10~(-4),影响不确定度的最大分量是样品重复性测试引入的不确定度。
According to the industry standard JC/T 984—2011 "Polymer Cement Waterproof Mortar",the shrinkage rate of waterproof mortar is measured by specific length meter. According to JJF 1059.1—2012 "Evaluation and Expression of Measurement Uncertainty",the sources of various uncertainties are analyzed and the uncertainties are evaluated. The measurement results of shrinkage rate is(2.376±0.1661)×10~(-4). The greatest component of the uncertainty is the uncertainty introduced by the repeatability of the sample.
