INFLUENCE OF THE ADDITION OF VARIOUS TYPES OF MINERAL ADMIXTURES ON THE ALKALI-SILICA REACTION IN CONCRETE
Original language description
The work deals with the alkali-silica reaction (ASR) in concretes and mortars, which is one of the possible causesof failures of concrete structures. The aim of the work was to study the effect of different supplementarycementitious materials (SCMs) on ASR. The results were evaluated using an accelerated expansion test accordingto ASTM 1260. Firstly, it was necessary to solve the issue of the low-reactive aggregate. These aggregates did notallow a clear evaluation of the effect of SCMs on ASR. This problem was solved by replacing a part of theaggregate with glass shards, which led to an increase in the reactivity. In addition, the effects of different amountand different glass fractions on ASR were studied. A subsequent experiment with SCMs showed a positive effecton ASR elimination for all tested SCMs. The greatest effect on ASR elimination was detected for fly ash togetherwith metakaolin followed by the Sorfix binder. The least effective was a blast furnace slag.
