Alkali-silica reaction (ASR) in concrete is a reaction between certain silicious constituents in the aggregate and the alkali-sodium and potassium hydroxide which are released during the hydration of Portland cement. A gelatinous product is formed which imbibes pore fluid and in so doing expands, inducing and internal stress within the concrete.
