Silica fume specific gravity

PROPERTIES State Amorphous - Sub-micron powder Color Gray to medium gray powder Specific Gravity 2.25 Solubility Insoluble Silica fume specific gravity is 2.2, which is somewhat lighter than portland cement, which includes a particular gravity of 3.15. Adding silica fume to concrete mix will not density the concrete. This expression means that silica fume isn’t a substance that is crystalline. The specific gravity of silica fume is generally in the range of 2.2 to 2.3.

1.2 In the cases of slurried or densified silica fume, perform the tests on the raw silica fume from which these products have been made.

Silica fume has a specific gravity of about 2.2, which is some what lighter than Portland cement, which has a specific gravity of 3.15 .Thus, adding silica fume to a .

Fumed silica is made from flame pyrolysis of silicon tetrachloride or from quartz sand vaporized in a 3000 °C electric arc. Major global producers are Evonik (who sells it under the name Aerosil), Cabot Corporation (Cab-O-Sil), Wacker Chemie (HDK), Dow Corning, Heraeus (Zandosil), Tokuyama Corporation (Reolosil), OCI (Konasil), Orisil (Orisil) and Xunyuchem(XYSIL). working with silica fume and silica-fume concrete. Different chapters of the Manual may be of interest to concrete specifiers, concrete producers, concrete contractors, or concrete inspectors.
