Abstract:This study evaluated the effects of combining varying proportions of slag cement and Class C fly ash
with Type I/II cement in concrete pavement. Three different ternary cementitious material combinations
containing slag cement and Class C fly ash (10% fly ash with 27% slag, 15% fly ash with 25% slag and 20%
fly ash with 24% slag) were combined with limestone coarse aggregate and a moderately-reactive fine
aggregate. Two concretes used only Portland cement. Specimens of each concrete from the project were
tested in the laboratory to evaluate physical properties. On-going pavement condition surveys will track
pavement performance.
All three ternary-blend concretes met specification requirements for the tests of alkali-silica
reactivity. The 10% fly ash-27% slag combination was the most effective in preventing expansion. The 10%
fly ash-27% slag concrete also had the highest strength and lowest permeability of the five concretes tested.
