水泥比表面积试验试测定是水泥细度的方法之一。细度大小反映了水泥颗粒粗细程度或水泥分散程度,它对水泥的水化速度、需水量、和易性、放热速率和强度的形成都有一定的影响。故试验的准确性直接影响到水泥的其它重要物理性能。本文通过多年的试验经验,对水泥及其它粉料的空隙率进行测定,并得出一些经验数据以及分析影响试验数据操作时的注意事项。
Test of cement specific surface area test is one of the methods of cement fineness. Fineness reflects the degree of cement particles or the degree of cement dispersion, cement hydration speed, water demand, workability, heat rate and intensity of the formation of a certain impact. Therefore, the accuracy of the test directly affects other important physical properties of cement. In this paper, through many years of experimental experience, the porosity of cement and other powder is measured, and some empirical data and analysis of the impact of experimental data operation precautions.
