Recently a number of examples of premature deterioration caused by alkali-silica reaction have been reported. This paper deals with concrete surface treatment adopted in maintenance work. The long term performance of typical surface treatments is examined and the effect of surface treatment on expansion of concrete due to alkali-silica reaction is investigated experimentally. The fundamental concept to determine the effect of surface treatment for alkali-silica reaction is discussed.
