Abstract
The concentration d3 is alumina AL2O3, —A—, and the concentration d4 in lime CaO, —C—, in the initial mixture are such that d3/d4 ranges between 1.15 and 1.40. Grinding produces a cement with a size distribution as represented in a Rosin Rammler diagram has a gradient ranging between 0.75 and 0.90.
