Effect of Alkali-silica Reaction on Delayed Ettringite Formation in Concrete

We investigated the effects of alkali-silica reaction (ASR) on delayed ettringite formation (DEF) using mortar test pieces comprising ASR reactive aggregates with added potassium sulfate under various environmental conditions. As a result, it was observed that ASR not only promotes expansion caused...
