Silica Fume is used in the manufacture of high quality concrete
Silica Fume is a very fine powder with an average particle size of 0.1-0.2 microns and a specific surface area up to 15,000-20,000 m2 / kg.
Using silica fume in concrete production will reduce the permeability of concrete, making the concrete more durable. The incorporation of ultrafine silica fume particles into the concrete mixture also produces a “lubricating” effect in the concrete due to the spherical shape of the silica fume particles. Therefore, the concrete mixture will still have more adhesion than the normal concrete mixture.
Advantages of using silica fume in the manufacture of concrete
– Improved relative strength of concrete by significantly reducing permeability of concrete;
– Increases early and ultimate strength both for compression and bending;
Extremely high strength concrete exceeding 15,000 psi compressive strength and 6,000,000 psi elastic modulus;
– Increased chemical resistance up to 15 times stronger than plain concrete;
– Increase density;
– Reduces damage caused by freezing and thawing;
– Increase the abrasion resistance of concrete;
– Reduce surface bleeding;
Effective corrosion inhibition system against the ingress of salt pollutants produced in water (reduced salt or sea salt);
