Densified silica fume. The densified version of the material is easier to
handle and more economical to transport than the as-produced fume.
Densified silica fume should not be confused with pelletized silica fume.
In that process, water is added to the fume to form small pellets. These
pellets become extremely hard and will not break down in a concrete mixer
during concrete production.
