混凝土强度合格评定问题探讨

Discussion on Conformity Assessment Issues of Concrete Strength

针对混凝土强度评定过程中容易出现错误或者存在一定争议的几个问题进行了详细的阐述,如样本容量取值、钻芯修正方法区别、计算过程中的一些约定和数值修约、碳化深度修约对结果的影响等,并通过工程实例详细展示了如何计算检验批推定区间上下限值、数值修约、推定区间的限制,如何对检验批进行合格评定的过程。

This paper detailed expounded some problems include error-prone and which had a certain controversy for concrete strength evaluation process,such as sample size value,correction difference to coring,some conventions in calculations and numerical revised,Carbonation depth rounding,it described the impact of the results of these questions and so on,and it showed details the process of how to calculate the estimated range of upper and lower limit inspection lot,numerical revised,presumption of interval,and how to carry on the conformity assessment of inspection lot.
