Abstract:This laboratory and field investigation studied the deicer scaling resistance of ground granulated blast furnace (GGBF) slag concretes. The laboratory part of the investigation used the ASTM C 672 test with up to four different curing routines: air, curing compound, the standard procedure, and intermittent wet cure. The field part evaluated three curing routines: air, curing compound, and intermittent wet cure. It also evaluated two different finishing tools, and the effect of a linseed oil-kerosene sealer applied at 90 days. Overall, regarding the effect of GGBF slag dose on scaling resistance, and relative to portland cement content: 25 percent improved resistance, 35 percent was better in the laboratory and similar in the field, 50 percent was variably better or the same or worse, and 65 percent scaled more in the laboratory and less in the field.
