The Determination of the Content of Addition of Silica Fume and the Relationship of Water/Binders in Uhpc Through the Wet Packaging Method.

The determination of the optimum amount of constituents, for UHPC production still needs studies, because in many cases this definition is empirical. This work aims to present a methodology for determining the amount of silica fume and to establish a water/binder ratio based on laboratory tests. To define the quantity of constituents necessary for the formation of the paste, the wet packaging method was used and the concentration of solids, the volume of voids and the excess of water were determined. The results indicated that the adopted methodology is adequate, leading to commonly used values.
