Condensed Silica Fume

CSF Condensed Silica Fume

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
