Composition Condensed silica fume consists primarily of pure silica in non-crystalline form and contains more than 90% silicon dioxide. Small amounts of magnesium, iron, and alkali oxides are also present. Most particles are smaller than 1 mm with an average diameter of 0.1 mm. ASTM C 1240 limits the percent retained on the 45-mm sieve to 10%, the moisture content…

Since microsilica particles are only about 1 / 100 the size of cement grains, the material may be hard to batch and ship. These handling problems may be overcome by mixing microsilica with water (and sometimes other admixtures) in a slurry which replaces part of the normal concrete mixing water. Densification and pelletization have also been tried to simplify the…

Physical properties of silica fume

Blog
Properties: Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 700 kg/m3 (densified). The specific…
