This test method permits detection within 16 days of the potential for deleterious alkali-silica reaction of combinations of cementitious materials and aggregate in mortar bars. The cementitious materials are composed of various proportions of hydraulic cement, pozzolans, and ground-granulated blast-furnace slag. The test results are only valid for the specific combinations of pozzolan, slag, and reactive aggregates tested.
