Lithium hydroxide and various lithium salts have been known to ameliorate the effects of alkali silica reaction for many years. The use of lithium hydroxide is not without risk. The development of a lithium-bearing glass has been reported as a means of minimizing this uptake of lithium by hydration products, thereby resulting in more efficient use of the active lithium compound in controlling ASR-induced expansion.
