基于正态分布从强度方面评价水泥质量的应用

水泥抗压强度检验值是评判水泥强度等级的主要指标，强度高低决定了混凝土配比水泥用量，也影响混凝土的制造成本。实际应用中，并非一味追求强度越高越好。对于同一强度等级的水泥，3d强度和28d强度各不相同。本文以正态分布为理论基础，运用方差理论，通过对水泥抗压强度检验结果的分析，从强度方面阐述引入标准值评价水泥生产企业的水泥产品质量。

Application of evaluating cement quality from strength based on normal distribution

The inspection value of cement compressive strength is the main indicator to judge the cement strength grade. The strength determines the amount of cement used in the concrete mix, and also affects the manufacturing cost of concrete. In practical application, it is complicated for cement selection. For cement of the same strength grade, 3-day strength and 28-day strength are different. In this paper, based on normal distribution and variance theory, through the analysis of the test results of cement compressive strength, the standard value is introduced to evaluate the quality of cement products of different enterprises from the strength aspect.
