On utilization and mechanisms of waste aluminium in mitigating alkali-silica reaction (ASR) in concrete

Alkali silica reaction (ASR) is one of the most commonly occurring durability issues in concrete structures. In this study, the feasibility of using waste aluminium in bit, powder and dissolved forms as a sustainable alternative to mitigate ASR was investigated. The accelerated mortar bar test was adopted for expansion measurement and mitigation mechanisms were explored with reactive glass dissolution, pore solution and microstructural analyses....
