Physical Properties                                          

Microsilica is an amorphous silicon dioxide (silica) consisting of sub-micron spherical primary particles and agglomerates of these. The material is highly reactive in cementitious and ceramic bond systems. The average diameter of a Microsilica sphere is about 0.15 micron. Although some of the spheres exist as single entities, most of them form primary agglomerates. The size of these may vary between 0.1 and 1 micron. This rather wide particle size distribution contributes to high packing efficiency. Microsilica will also contain secondary agglomerates (typically 5 - 50 microns), often generated during filtration and collection. These are - unlike the primary agglomerates - easily broken down when the powder is dispersed in a liquid. Pure silica powder  has no internal porosity, and the specific gravity of pure silica powder is about 2.3 g/cm3 . The specific surface area may vary between 15 and 30 m2 /g.
