Zusammenfassung:Multiple linear regression and factor analysis were used to study the influence of the clinker features (mineralogical composition, specific surface area, degree of crystallinity (crystallite size and strain) of alite, and crystallite size of C3A) on the 1, 3, 7 and 28-day compressive strengths of a series of Portland cement mortars with very high C3A contents. A mathematical model based on the linear weights of the considered variables, which may help in understanding the complex hydrolysis of minerals in Portland cement, was employed. A large set of clinkers from "Portland de Mallorca" where alite, belite and tricalcium aluminate occur essentially in their rhombohedral, beta and cubic forms, respectively, and the ferrite phase occurs in its rhombic form, were chosen. Hourly samplings were performed in order to obtain a daily average clinker. 18 refs.
