Quality Silica Fume
From Ecotec Silica Fume

Ecotec 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.

It is 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 Ecotec 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. Formerly known as Restec Silica Fume, the name change to Ecotec Silica Fume better reflects the product's environmental preferability.

Ecotec Silica Fume is distributed Australia wide and stock is available via our warehousing facilities in Melbourne, Sydney, Brisbane, Adelaide, Perth and Darwin.

Level One Registered Supplier - Transport and Main Roads QLD

Ecotec Silica Fume is registered as an approved supplier of Silica Fume for Main Roads Projects.

Ecotec Silica fume consists of very fine particles. The particle size is approximately 100 times smaller than the average cement particle. Because of its extreme fineness and high silica content, silica fume is a highly effective pozzolanic material. Being a highly reactive pozzolan, silica fume chemically reacts with the calcium hydroxide present in the cement paste, creating a stronger calcium silica hydrate "making it sticky". The result is improved paste to aggregate bond (excellent for shotcrete) and higher concrete strengths.

Ecotec Silica Fume is typically grey in colour and is categorised as a supplementary cementitious material (SCM). Ecotec Silica Fume is compliant to AS/NZ 3582.3:2002 and is described as a Densified Amorphous Fumed Silica.

Ecotec Silica Fume can be used to produce all grades of concretes. The chemical and physical properties of Ecotec Silica Fume can greatly enhance the strength performance and the bonding properties of concrete.

Ecotec Silica Fume can be used in various applications and projects: Commercial, Civil, Mining and Marine projects.
