摘要
从理论上分析了水泥细度对其性能的影响,指出提高粉磨细度一方面可以加速水泥的水化,但另一方面也将提高需水量。必须综合考虑这两个方面的影响,才能使水泥达到较好的性能。因此,存在着一个最佳的粉磨细度。分析并计算了四个系统的最佳粉磨细度。计算结果表明,在通常的情况下,水泥的比表面积不应超过3500cm^2/g。
The influence of the cement fineness on its property is analyzed theoretically.It is shown that raising milling fineness can accelerate the hydration of cement,but raise water requirement too.Only by considering them synthetically can cement have good property.Thus there is an optimum milling fineness.The optimum milling fineness of 4 systems is analized and calculated.The result shows that under normal circumstances, the specific surface of cement should not be over 3 500 cm^2/g.
