Condensed Silica (Silica Fume) and Amorphous Silica Superdispersed Powder From Russia

Ladies and Gentlemen! Our Company expresses you our Respect! Firm «ASEAN INTERNATIONAL HOLDINGS Ltd» offers you to consider the possibility of purchasing and utilization of super active concrete and mortar filler material from Russia. Condensed silica (CS, Silica fume) constitutes amorphous silica superdispersed powder of grey color. Bulk weight depending on compacting method is 150-250 kg/m3 (noncompacted), 280-500 kg/m3 (compact). Present mount is irreplaceable under such huge construction, - to get concrete of extreme stability and waterresistance (sky-scrapers, overpasses, bridges, tubes for undergrounds, basements) - to enhance concrete durability under the influence of acid and high temperature (constructions on chemical plants, metallurgical shops constructions) - to replace part of concrete (up to 30-40%) in retention of solution and concrete stability (at oil and gas fields, oil well cementing); - to improve the quality of concrete products, made of hard and easy workable mixes (mainly in seismological zones, airport and firing pad construction); - to reduce power inputs for thermal treatment of concrete products owing to cutting down its duration. A number of constructions Such as a complex of high-rise buildings in Chicago, the tunnel under the La Manche, a bridge through the Nortumberland strait in Canada, bridge through Akasi channel in Japan with the central bay of 1990 m, bore platforms in the Norwegian sea, high class highways, etc. have been constructed with the help of microsilicia. Besides, microsilicia as an asbestos substitute finds a wide application for production of tile and mineral slabs, is used in production mixtures, refineries, refractory pastes, etc
