By high final strength cements are mainly understood those Portland cements with a mark superior to that of I 52.5 type cements. Such cements may be obtained by providing an adequate mineral composition, namely a highly reactive morphology and crystal-chemical structure of the used clinkers, as well as a high grinding finesse, adequate to the resulting cements, associated with an advantageous grain size distribution for the development of some highly resistant hardening structures. This paper aims to a comprehensive approach, with regard to obtaining final high strength cements, in correlation with the decisive influencing factors – intrinsic and extrinsic, mentioned above. These factors are, in turn, conditioned by the oxide and mineral composition of the precursor mixes – intrinsic factors, as well as by processing parameters, by the thermal treatment applied and by the grinding conditions, used as extrinsic factors; all these factors together are conditioning the phase composition and the morphological and mineralogical characteristics of the clinkers, the dispersion parameters of the obtained cements, respectively.
