Chemical approaches to prevent alkali-silica reaction in concrete – A review

Abstract: This study synthesizes the use of chemicals to prevent one of common concrete durability problems, alkali-silica reaction (ASR), and can help researchers (i) identify widely used potential chemicals and evaluate these chemical solutions to prevent ASR with proper understanding of mechanisms, and (ii) to identify the research gaps in order to develop guidelines and implementation plan on the use of these chemicals for future research.

“…The screening tool uses WSA from both fly ashes in addition to soluble alkali from cement to determine the net PSA of concrete mixes for different fly ash replacement levels. The optimum fly ash dosage for ASR mitigation in concrete is estimated based on PSA and aggregate THA relationship (PSA should be ≤THA to mitigate ASR) ( 2 , 3 , 24 ). The following work items were undertaken to achieve the primary objective.…”
