This text investigates the chemical mechanisms and structural implications of alkali-aggregate reaction (AAR) in concrete infrastructure. The authors, Sims and Swamy, provide a technical examination of how reactive aggregates interact with cement alkalis to cause expansion and cracking. By synthesizing laboratory data and field observations, the work establishes a framework for identifying, monitoring, and mitigating the degradation of concrete structures over time.

Experts in civil engineering and materials science recognize this work as a technical reference for managing concrete durability. Readers frequently note the high density of the chemical data and the practical focus on structural integrity assessments.
