clinker grinding fineness with regard to the initial grain size distribution (Fig. 2). The studies for clinker with a height of embankment from 10×10-3 to 40×10-3 m, with a constant pressing pressure of 50 MPa have been conducted. Graphic analysis of Fig. 2 made it possible to establish that with an increase in the initial clinker
