Abstract:
Fresh, early-age, and hardened concrete properties were evaluated in a laboratory investigation of forty SCC mixtures proportioned using: two types of coarse aggregate—crushed limestone and natural gravel; three nominal maximum sizes of aggregate (NMSA)—¾, ½, and 3/8 in.; three SCMs and one filler—25% Class F fly ash, 25% Class C fly ash, 30% ground granulated blast-furnace slag (GGBFS), and 20% Class F fly ash +15% limestone powder (LSP); and two levels of slump flow—low (22–26 in.) and high (26–30 in.). All SCC mixtures were air entrained and contained Portland cement Type I/II. The laboratory tests were conducted according to AASHTO or ASTM methods. Measured properties of SCC mixtures were compared to predicted values using existing prediction models.
