混凝土抗压强度测量不确定度评定

混凝土抗压强度试验是评定混凝土工程质量的重要手段，通过对混凝土抗压强度测量结果不确定度评定，分析了荷载、试件截面尺寸、检验重复性、数据修约等影响测量结果不确定度的因素和来源，对各分量进行了计算合并，并作出了评定，为提高测量水平提供指导。

Evaluation of uncertainty in measuring the concrete compression strength

Concrete compressive strength testing is an important means of assessing the quality of the concrete work,which applies to construction,water conservancy,transportation and other related industries.According to laboratory accreditation and measurement certification requirements,testing laboratories for testing must be assessed for uncertain evaluation.The authors studied the criteria for evaluation about uncertain degree of measurement and embarked on the evaluation of uncertain degree of compression strength of concrete.They also analyzed the main factors affecting measurements of uncertainty and provided guidance to improve the measurement level.
