Reports of remedial work or catastrophic failure of structures due to alkali-silica reaction is rare. The collapse of a two-year-old pipe as a result of alkali-silica reaction aggravated by dissolved sulfates in the pipe's effluent provides a case history that demonstrates the limitations of our ability to use aggregates including reactive constituents.
