Elkem Microsilica® - filling your needs
Elkem Microsilica® is one of the principle products supplied by Elkem Materials. It finds a wide range of applications in high-strength concrete, other building materials such as roof tiles and facade cladding, and fire-proof products for heavy industry. Microsilica is also used for sealing tunnels and drilling oil-wells.
This product comprises microscopic particles collected by filters downstream from the smelting process in silicon and ferrosilicon plants. Adding it to concrete and other materials increases their density and wear resistance, which extends the life of structures. Microsilica has been delivered by Elkem to a number of major projects in Norway and internationally, including the Øresund/Great Belt connection.
Elkem Materials also produces Ceramite, a fire-proof material which is particularly heat-resistant and hard-wearing. Treatment technology has been supplied by Elkem to industries world-wide for many years, and the company is currently involved with major filtration projects in China. This way, environmental solutions developed by Norwegian industry help to deal with pollution problems in other parts of the world.
