Strengthening & protective applications

Microsilica is commonly used in the production of fibre cement. ELKEM MICROSILICA^® acts as an interactive filler and a highly reactive pozzolanic ingredient in fibre cement recipes.

The construction industry is constantly seeking ways to improve the durability and sustainability of concrete structures. Since the early 1980s under the ELKEM MICROSILICA^® brand, Elkem has developed a unique range of silica fume products to improve the performance and durability of concrete.

Gypsum board – also referred to as drywall, wallboard or plaster board – has become the most convenient and widely used material for interior wall and ceiling coverings. These practical gypsum panels have replaced traditional plastering for several reasons

The growing demand for higher-performance steels is placing ever-greater emphasis on the quality of ferrosilicon (FeSi) alloys used in steel manufacturing plants – and at Elkem, we’re ready to help you make the best decision for your business.

The building & construction industry has to meet exacting standards to be compliant with industry codes for residential, commercial, and industrial buildings.  Creating these materials may require a siliconized liner to transport these materials to the building site, yet provide consistent and stable release during any time of year or environment – from the hot blazing summer sun, to the frigid temperatures of winter.  

By incorporating silicon, aluminum gains enhanced corrosion resistance and durability, making it suitable for harsh environments. Additionally, silicon imparts greater tensile strength, crucial for structural components. This combination ensures longevity and reliability in construction materials, safeguarding buildings against wear and environmental stressors. Silicon's integration with aluminum is indispensable in fortifying structures, ensuring safety, and prolonging the lifespan of construction projects.

Most construction materials are porous to a greater or lesser extent and, if left untreated, are prone to water infiltration and damage caused by rain, dampness or humidity. Builders of homes, offices and industrial facilities are increasingly demanding materials that have been pre-impregnated or coated with hydrophobic emulsions to streamline the construction process and comply with increasingly strict regulations. These pre-treated materials used for foundations, structural walls, grouting, cladding and roofing can vary from stone to sandstone, via concrete, bricks, earthen tiles, sandstone, etc.

Buildings of all sorts – residential, offices or commercial – have always been constructed and continue to be made with a variety of mineral materials: brick, stone, concrete, cement cladding, granite, marble, etc. All of these minerals have variable porous surfaces and are today exposed to more severe environmental and man-made pressures than ever.
