Multiplast AlkaSil
Aggregates form a major component of the concrete mix. Certain constituents in aggregates can react with alkali hydroxides in concrete. This reactivity is potentially harmful only when it causes significant expansion, typically becoming visible after a decade. This alkali-aggregate reactivity (AAR) has two forms—alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR, sometimes called alkali-carbonate rock reaction or ACRR). ASR is more often a concern than ACR because reactive silica minerals in aggregates are more common. Multiplast AlkaSil is designed to prevent alkali-aggregate reaction.
