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 cement, 15 SF and 20 FA at the W/Fv ratio of is the optimum mixture proportions for the highest compressive strength of the UHPC. | Study on using maximum amount of fly ash in producing ultra high performance concrete
