silica fume powder

It has been identified as one of the more important advanced materials necessary in the effort to rebuild the nations infrastructure. In addition to increased strength and enhanced durability, HPC produced with silica fume delivers increased toughness; increased resistance to abrasion, corrosion and chemicals; and placement and life-cycle cost efficiencies. Very low permeability to chloride and water intrusion.Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete).Increased abrasion resistance on decks, floors, highways and marine structures.Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates.
