This study deals with the durability of immobilization matrices, drawing comparisons among the release characteristics of cementitious mortars with or without silica fume, before and after freezing-thawing cycles. Three different dosages of silica fume have been experimented, using silica fume as a substitute of cement.

Abstract

This study deals with the durability of immobilization matrices, drawing comparisons among the release characteristics of cementitious mortars with or without silica fume, before and after freezing-thawing cycles. Three different dosages of silica fume have been experimented, using silica fume as a substitute of cement. The results obtained from the leaching tests have emphasized, in all the matrices which had undergone the freeze-thaw cycles, an increase of the percentage of tracer released with respect to the same matrices before the freezing-thawing cycles. As a consequence of the freezing-thawing cycles, the velocity of release has also increased in all the experimented matrices. However, the tests have reconfirmed the positive effect of the addition of silica fume.
