Restec Silica Fume is a high performance, densified silica fume powdered product, derived as a by-product from the production of Ferro Silicon using the arc furnace method. Used in pre-mixed concrete for enhancing mechanical properties of concretes with special performance requirements, including increased strength, reduced permeability, improved abrasion resistance and increased corrosion resistance.

The addition of Restec Silica Fume can provide:- Increased compressive strength, Increased abrasion resistance, Enhanced sulphate resistance, Reduced chloride ion permeability, Enhanced resistance to chemical attack and deterioration, Improved durability, Increased bond strength.
