水泥组分的定量测定应用于合格评定的可靠性研究

Reliability study of quantitative determination of cement composition in conformity assessment

为了研究《水泥组分的定量测定》(GB/T 12960—2019)应用于合格评定的可靠性,通过采集不同种类的混合材参照水泥产品标准中对水泥组分的相关规定,在实验室精确配制不同水泥组分的水泥样品,采用《水泥组分的定量测定》(GB/T 12960—2019)进行测定。通过研究,发现采用GB/T 12960—2019测定水泥组分准确率较低、可靠性较差,应用于合格评定存在较大风险。同时,结合对水泥组分测定方法的思考,提出了规范水泥组分的若干建议。

In order to study the reliability of"Quantitative Determination of Constituents of Cement"(GB/T 12960-2019)applied in conformity assessment,cement samples of different cement components were accurately prepared in the laboratory by collecting different types of admixtures and referring to the relevant provisions of cement components in the cement product standard.Quantitative determination of cement constituents of cement(GB/T 12960-2019)was used for determination.Through the study,it was found that GB/T 12960-2019 determination of cement composition has low accuracy and poor reliability,and there was a great risk when it was used in conformity assessment.At the same time,considering the determination method of cement compositions,some suggestions were put forward to standardizing cement components.
