本报告旨在介绍ACI 214中概述的统计概念的简化版本，用于混凝土生产的规范、控制和评估。有关这些概念的更详细讨论，请参阅“混凝土强度试验结果评估推荐规程（ACI 214）”

The purpose of this report is to introduce the use of a simplified version of the statistical concepts as outlined in ACI 214 for the specification, control, and evaluation of the production of concrete. For a more elaborate discussion of the concepts, see "The Recommended Practice for the Evaluation of Strength Test Results of Concrete (ACI 214)."
