To investigate the long-term durability of concrete made with an alkali-silica reactive coarse aggregate, six concrete mixtures were made with various cementing materials: high-alkali portland cement, low-alkali portland cement, 25 percent ground granulated blast-furnace slag (GGBFS), and 50 percent GGBFS with high-alkali portland cement, 18 percent Type F fly ash with high-alkali portland cement, and 3.8 percent silica fume with high-alkali portland cement and 25 percent GGBFS. The three conditions under which concrete slabs were cast and cured included: 14 days in the moist room at 23 deg C, 14 days outdoors covered under wet burlap and plastic sheet, and 28 days in the laboratory air after applying a curing compound. The slabs were tested at day 28 for 50 freeze-thaw cycles in the scaling test using a 3 percent sodium-chloride solution. The slabs cured outside had a high resistance to scaling, with the exception of the mixture with 50 percent GGBFS. This same concrete also exhibited scaling of a full-scale outdoor slab on grade during the first winter. The slabs cured in the moist curing room, according to the test method, generally showed a low resistance to salt scaling.
