Overall, the procedures for this aspect of the work are not different from those of concrete without silica fume. The Silica Fume Association 38860 Sierra Lane, Lovettsville, VA 20180

Silica fume can also be pelletized, whereby the silica fume is mixed with water and some cement. The silica fume pellets can be ground with Portland cement clinker to form a blended cement. Irrespective of the delivery form of silica fume (i.e., as-produced, compacted, slurried, or pelletized), similar concrete properties and performance can be achieved ( Hooton, 1993; Zhang, Zhang, & Yan, 2016 ).
