Silica fume is available in all of the product forms shown in this slide.
Further, these product types may be available in bulk, bags, or drums as
appropriate for the material and for the size of the project. Except as
noted below, there is no generally accepted data that indicates that any
form of the product out-performs any other form when used in concrete. Each
of these product forms is described in the next few slides.
Silica fume in the pelletized form is not suitable for direct use in
concrete because the pellets will not break down and disperse in a concrete
mixer. Pelletized silica fume can be interground with portland cement
clinker to produce blended silica-fume cement.
