| Popis: | This article concerns marginal variations in the functional properties of very-high-strength mortars and concretes resulting from the type of silica fume used. Twenty silica fumes were tested, in the presence of two cement-superplasticizer pairs. All of the results are analysed into main components and regressions. The action of carbon on the workability of the mixtures has been verified. Finally, within the limits of the scattering of the results, it has been possible to establish an empirical law, fitted to previous results, showing the influence of the alkali content of the silica fume on its pozzolanic activity. |
