silica fume as a “very fine non-crystalline silica produced in electric arc furnaces as a by-product of the production of elemental silicon or alloys containing silicon.
The amount of silica fume is determined based on the amount of cementitious material, usually from 5% to 10% of the cementitious material.
Most silica fume colors range from light gray to dark gray. Because silica is colorless, the color is determined by the non-silica component, which typically includes carbon and iron oxide.
Universal product packaging is the use of tons of bags, we can not add any LOGO, but also customers can choose.
Typically, most silica fume particles are less than 1 micron in diameter, However, after being densified processed, the particles will be brought together to form larger particles ranging from a few microns to tens of microns.
First you need to send an email or leave a message on the website, we will arrange a salesperson to contact you to confirm the type and weight of the sample, you can choose DHL or FedEx.
The specific gravity of silica fume is about 2.2, while the specific gravity of Portland cement is about 3.1.
