Abstract
The present study envisages the potential alkali–silica reactivity; the most common form of alkali aggregate reaction of various aggregate sources of Kashmir and mitigation measures thereof using petrographic analysis and various designated ASTM codes. The chemical analysis was carried out for different aggregate samples possessing different lithology hence varied reactive nature. Comparatively some samples showed more reactive nature than others due to presence of higher reactive silica. The results show the innocuous nature of all aggregate samples according to ASTMC-289 standard curve. The study reveals that addition of Fly ash reduced the elongation of bars resulted due to alkali silica reactivity of the aggregates and hence should be widely used as a mitigation measure to overcome the alkali reactive nature of the aggregates in the region.
