A large portion of this report discusses the construction and design of an outdoor exposure site built at the University of Texas at Austin where the goal was to cast field representative concrete elements with laboratory precision and expose them to real environmental conditions. The elements were monitored for expansion and deterioration. At discrete expansion levels a range of mitigation methods were implemented on the structures. After the concrete elements were treated, long-term monitoring was conducted to determine the best approach to provide effective suppression of alkali-silica reaction in the various element types.application/pdfen-USAlkali-silica reactionExposure siteHardened concreteSilaneLithium nitrateVacuum impregnationElectrochemical impregnationOverlayFiber reinforced polymer2013-11-21
