Abstract: A practical alkali-reactive aggregate—Beijing Aggregate— was used to test the long-term effectiveness of LiOH in inhibiting alkali-aggregate reaction expansion.
In this paper, not only the most rigorous conditions, such as the mortar bars being cured at 80°C, for 3 years, and autoclaved 24 hours at 150°C, but also the 20°C long-term curing condition were designed.
At these conditions, LiOH was also able to inhibit ASR expansion long-term effectively.
Not only the relationship between molar ratio of n(Li)/n(Na) and the alkali contents in systems was established, but also the governing mechanism of such effects was also studied by SEM and EDS.
