✦ Synopsis

Multiple linear regression and factor analysis have beenused to investigate the influence of the clinker features (mineralogical composition, specific surface area, strainscrystallite size of alite and crystallite size of CA) on the I, 3, 7 and 28-day compressive mechanical strength of a series of Portland cement mortars of very high C,A contents. A mathematical model based on the linear weights of the considered variables that might be of help to understanding the complex hydrolysis of minerals in Portland cement has been employed. A large set of clinkers from "Portland de Mallorca" where alite, belite and tricalcium aluminate occur essential1 41

in their rorrbohedral, beta and cubic forms, respective y, and the ferrite phase occurs in its rhombic form has been chosen. We performed hourly samplings in order to obtain a daily average clinker.
