基于正态分布评价水泥强度质量的应用

水泥强度检验值是评价水泥产品质量和水泥强度等级的关键性技术指标,强度检验值不仅影响水泥混凝土配合比设计,还影响水泥混凝土的生产成本。为了评价水泥强度质量,提出了一种基于正态分布的评价方法。确定水泥质量的评价方法是通过对不同水泥生产企业相同强度等级的水泥强度进行检验,在判断检测数据符合正态分布规律的前提下,采用标准值作为评价指标来判断水泥质量的优劣。这种应用数理统计方法评价水泥强度质量的方法为用户购买和使用水泥提供了一种方法,可以在满足需求的情况下选择和使用合适的水泥产品。

The strength test value of cement is a key technical index to evaluate the quality of cement products and the strength grade of cement.The strength test value not only affects the mix design of cement concrete,but also affects the production cost of cement concrete.In order to evaluate the strength and quality of cement,an evaluation method based on normal distribution is proposed.The evaluation method to determine the cement quality is to test the cement strength of different cement manufacturers with the same strength grade,on the premise that the test data conforms to the normal distribution law,the standard value is used as the evaluation index to judge the quality of cement.This method of evaluating the strength and quality of cement using mathematical statistics provides a method for users to purchase and use cement,and can select and use appropriate cement products under the condition of meeting the demand.
