It is difficult to ensure enough workability and flowability in the fresh state of UHPC. In addition,
it needs to enhance economic efficiency by reducing the usage of expensive constituents. Zirconia silica fume is an alternative material to replace the existing Silica fume. The objective of this study is to find out the effect of Zirconia silica fume dosage on viscosity of UHPC matrix
