In the present study, the synergic effects of cementitious materials in the ternary binder containing cement, silica fume, fly ash on the workability and compressive strength were evaluated by using the D-optimal design of Design-Expert 7. The ternary binder composed of 65 vol.-% cement, 15 vol.-% SF and 20 vol.-% FA at the W/Fv ratio of 0.50 is the optimum mixture proportions for the highest compressive strength of the UHPC. To produce the sustainable UHPC, high-volume fly ash ultra high performance concrete with a good flowability and 28-d compressive strength over 130 MPa can be produced with fly ash content up to 30 vol.-% in the binder.
