Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. The main field of application is as pozzolanic material for high performance concrete.
Silica Fume applications:
Concrete, Cementitous Repair Products, Concrete Tile & Panels, FCB, Concrete Roofing & Wallboards, Shotcrete, Oil Well Grouting, Polymers & Elastomers, Repair Products, Refractory & Ceramics, Self-Consolidating Concrete and Ultra High Performance Concrete.
Q. How is color affected when using silica fume?
A. Silica fume is gray, changing along with different density. Concrete with silica fume will be darker in color.
Q. Are there any special requirements for placing, finishing and curing concrete with silica fume?
A. Yes. Since silica fume concrete has a low water cement ratio, it is important to prevent drying and moist curing is very important. For additional information please contact us.
Q. Is silica fume harmful to humans?
A. No. Silica fume is an amorphous form of Silicon and does not promote silicosis in humans. However, respirators are required for handling the product, since silica fume particles are very small and can easily become airborne.
Q. Are Silica Fume and Fumed Silica the same?
A. No. Silica fume is a by-product of steel production. Fumed Silica is a precipitated form of silicon dioxide that is produced chemically. Fumed Silica is much more expensive that Silica Fume and does not provide the same characteristics to concrete.
Q. Will you supply free samples?
A. Yes,it’s available. We ‘d love to provide free sample.
Q. How soon you can get the samples?
A. 1-2 days are needed for preparing samples.
