New approach in mitigating damage caused by alkali–silica reaction

Alkali–silica reaction (ASR) is a chemical reaction between the alkali and hydroxyl ions produced by portland cement hydration and certain types of silica present in the aggregate. The stages that are involved in causing damage due to ASR are shown schematically in Fig.  1. The alkali ions and hydroxyl ions in the pore solution of the hydrated cement paste react with amorphous or poorly crystalline silica in the aggregates to form alkali silica (AS) gel. The AS gel expands by imbibing water and the resulting pressure exerted onto the surrounding mortar matrix causes extensive cracking and strength loss.
