Abstract:

Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are expansive reactions that can lead to the premature deterioration of concrete structures. Both have been implicated in the deterioration of numerous structures around the world, including many transportation structures in Texas. Research on various aspects of ASR has been conducted since the late 1930s and has led to the identification of the mechanism of the reaction and subsequent expansion, as well as measures to prevent its occurrence in new construction. It consists of a reaction between alkali hydroxides in the pore solution and certain forms of silica in aggregate particles; with sufficient moisture, the product of the reaction swells and leads to expansion and cracking of the concrete. Eliminating any one of these components will prevent deleterious effects.
