Influence of Granulometric Cement Characteristics on the Uniformity Degree

In industrial practice, the dimensional characterization of the polygranular materials can be done, experimentally and/or by calculation, on the basis of various types of granulometric distribution laws, of the different types of diameters, of the specific surface and of some indicators related to the granulometric uniformity. This paper aims at introducing a new indicator, called granulometric uniformity degree, defined on the basis of some informational statistics elements, and calculated in a unique way, different from any particular type of granulometric distribution. At the same time, a series of correlations between the granulometric uniformity degree and different characteristic diameters is pointed out, i.e. the specific surface of cements, characterized by the Rosin-Rammler-Sperling ganulometric distribution.
