Discussion of Paper "Alkali-Aggregate Reaction in Concrete Containing High-Alkali Cement and Granite Aggregate" by Z. Owsiak

The original paper discusses the occurrence of the alkali-silica reaction (ASR) and the formation of secondary ettringite in concrete prisms under certain storage conditions. The discusser responds with his own observations that ASR and delayed ettringite formation are found in field concretes and in steam-cured laboratory concretes. The discusser concludes that ASR preceded secondary ettringite formation and this accounts for the large amount of ettringite in the samples seen by the original author.
