Alkalies, Chlorides, Seawater, and ASR: Is There an Increased Likelihood of a Harmful Alkali-Silica Reaction in Concrete Exposed to Seawater?

The author argues that the commonly accepted concept of not using potentially reactive aggregates in concrete exposed to seawater is false. The author states that the reason may be due to misleading information in technical literature regarding alkalies, which do not exist in seawater. The author argues that in most published papers, the word "alkali" is almost always without definition and misused. Alkali-silica reaction (ASR) severity is unlikely to increase when sodium chloride-based deicing salts are applied to concrete exposed to seawater. Correct use, as well as misuse, of the word "alkali" are discussed, as well as consequences of using incorrect definitions.
