✦ Synopsis

Data from new experiments and from work published during the past 40 years are subjected to regression analysis to determine the relationship between strength and the composition and fineness of cement.

The original authors differed in their opinions on the relative importance of CRS* and CRA. The controversy is examined against a background of ~xperienc~ with a group of materials that are representative of Portland cement in general, and in terms of an analysis based on a model in which, during the first weeks of hardening, the strength developed by C3S depends on the proportion of C3A in the cement.

Previous work has shown that, for a series of experimental autoclaved aerated concretes with porosities ranging from O.48 to 0.78, compressive strength is linearly related to the solid/pore volume ratio determined by helium pycnometry. In the work described here, this type of relationship has been

In as series of cements made out of clinkers with variable C3A/C4AF ratios and containing different amounts of gypsum, the strength development and the composition of the hydrated material were studied. For a single clinker composition the obtained strength appears to be just a function of porosity.
