ELKEM MICROSILICA® product, the original and market-leading silica fume for construction
Faster, higher, stronger
As populations increase and urban areas grow, space becomes a premium and construction projects become increasingly challenging. In addition, the demands for sustainable construction require the need for more resilient structures with a longer service life and lower maintenance costs.
The addition of silica fume enables concrete, fibre cement and gypsum boards to achieve improved performance levels to enable advanced building structures. Elkem, the world’s leading manufacturer and supplier of silica fume, offers a unique range of benefits that builders need and that regulators demand.
From start to finish
The advantages of silica fume in concrete starts at the beginning of construction.
ELKEM MICROSILICA® product improves the working properties of fresh concrete, making the mix easier to pump and improving workability, reducing any segregation and giving better cohesiveness.
ELKEM MICROSILICA® product gives early strength to allow faster development, saving time and money on construction. With several production facilities worldwide, Elkem is able to provide supply chain reliability, ensuring on-time and uninterrupted deliveries of our products through our global network. Through extensive testing as an ISO registered company, Elkem ensures consistency in ELKEM MICROSILICA® product to make sure that what we deliver is always in accordance with customer specifications.
Leading the market through quality and innovation
ELKEM MICROSILICA® product was introduced in the 1980s and is the original and market-leading silica fume powder, that has constantly been improved to meet the operational requirements of our customers.
Silica fume is an industrial by-product made of recovered ultra-fine amorphous silica particles produced during the manufacture of metallurgical silicon and ferro-silicon alloys in electric arc furnaces. ELKEM MICROSILICA® product is available in both powder and slurry options.
ELKEM MICROSILICA® product is tailored to specific construction needs to resist the harshest and most extreme environmental conditions. For example, concrete containing ELKEM MICROSILICA® product is highly resistant to chemical corrosion. Microsilica improves the durability and resistance of concrete to sea water. Therefore, concretes incorporating ELKEM MICROSILICA® product are frequently used in marine applications such as long sea bridges, sub-sea tunnels, coastal structures and offshore wind farms.
