✦ Synopsis

The Authors describe an attempt of correlating, by means of the linear regression analysis, the chemical composition of the Portland clinker to the compressive strength of blast furnace slag cements. The investi gation shows Chat the main constituents of the clinker do not influence the compressive strength of the slag fraction, which, in turn, is influenced by the alkali content of the clinker. Although it has been not yet possible distinguishing the rSle of soluble alkalis from that of the total content, nevertheless compressive strength of blast furna ce slag cements appears to depend upon two different and opposite contributions pertaining to the clinker fraction, negatively affected by its alkali content, at least at medium and long ages and the other belonging to the slag fraction, positively influenced by the same alkali content.
