由水泥颗粒比表面积引发的思考

Reflection upon specific surface area of cement particle

结合教学实践,详细推导了水泥颗粒粒径的大小与水泥比表面积之间的换算关系,得出了粉粒状物料比表面积的计算公式Sn=43nπR21,并给出了水泥颗粒比表面积的大小对水泥物理力学性质的影响情况,以期为学习水泥专业的人士提供指导。

Combining with teaching practice, this article specifically deduces the mutual matrixing relation between cement particle size and spe- cific cement surface area, and obtains the calculation formula Sn=4^3√nπR1^2 of specific surface area for powdered or granular materials,and then shows the influential conditions of cement particle specific surface area size on cement physical chemic performance, with a view to provide guid- ance for personnel specializing cement.
