Home / Applications / Silica Fume for Concrete

Silica fume presents a neutral inorganic filler with incredibly stable chemical and physical properties. It does not participate in the curing reaction, does not contain crystalline water, and does not affect the reaction metabolism.

Being an effective pozzolanic material, silica fume is commonly added to concrete to improve its properties, in particular bond strength, compressive strength, and corrosion resistance.

Adding silica fume to concrete can increase thermal conductivity and flame retardant, as well as change adhesive viscosity.

The addition of silica fume allows reducing epoxy resin’s exothermic peak temperature of curing reaction, the shrinkage rate of solidified products, and their linear expansion coefficient. This allows preventing cracking by eliminating internal stress.

It has great adsorption performance, produces no agglomeration phenomenon, is easy to mix, and offers good infiltration for various types of resin.
