Report on Alkali-Aggregate Reactivity

Description In many parts of the world, precautions must be taken to avoid excessive expansion due to alkali-aggregate reactivity(AAR) in many types of concrete construction. AAR may involve siliceous aggregates (alkali-silica reactivity, ASR)or carbonate aggregates (alkali-carbonate reactivity, ACR),and failure to take precautions may result in progressive deterioration, requiring costly repair and rehabilitation ofconcrete structures to […]
