Our Products - Norchem

Our Products: Silica fume is a mineral admixture, composed of submicron particles of silicon dioxide, manufactured as a co-product from the production of silicon and ferrosilicon metal. When added to concrete, silica fume acts as both a filler, improving the physical structure by occupying the spaces between the cement particles and as a 'pozzolan,' reacting chemically to impart far greater ...

What is silica fume?

A. Silica fume is very fine noncrystalline silica produced in electric arc furnaces as a byproduct of the production of elemental silicon or alloys containing silicon.(ACI CT). The average size of a silica fume particle is about 100 times smaller than an average portland cement particle. It acts as a mineral filler and also as a pozzolan, leading to concrete of high strength and low ...

Understanding the Role of Fumed Silica in Adhesives and ...

02/09/2014  Formulators use particles to enhance the functionality of existing polymer matrices for adhesive and sealant products. Fumed silica is commonly used as a rheology control additive to provide sag resistance, anti-settling of fillers and shear-thinning viscosity. The generic term “fumed silica” defines a range of products with different surface chemistries—from hydrophilic to hydrophobic.
