ABSTRACT:
Compositions for controlling damage to cementitious materials as a result of alkali-silica reactions (ASR) are provided. The compositions include a lithium containing material and a surface active agent. The compositions are capable of effectively delivering lithium into a cementitious material after the composition is applied to a surface thereof. Processes for treating cementitious materials using the compositions are also provided.
