To date, blended silica-fume cement has not been used to any real extent in
the US. This lack of use may be attributed to these factors: 1) Lack of
flexibility in silica fume dosage; 2) Limited volume of concrete that can
be produced from one truckload of blended cement; and, 3) Difficulty in
batching concrete for small projects.
Densified or pelletized silica fume must be interground during production of
blended silica-fume cement to ensure dispersion of the agglomerates.
