How our minerals enhance the construction industry
The construction industry relies on high-quality minerals to improve durability, efficiency, and the responsible sourcing of materials. At LKAB Minerals, we supply a broad range of mineral solutions that enhance construction materials, ensuring stronger, more resilient, and responsible structures. But which minerals play a crucial role in modern construction, and how do they contribute to building better infrastructure?
The role of minerals in construction
Minerals are essential in nearly every aspect of construction, from cement production and concrete reinforcement to fireproofing and decorative finishes. Their unique properties provide strength, durability, and thermal stability, ensuring structures meet the highest performance standards while aligning with responsible sourcing goals.
Key minerals enhancing the construction industry
Aluminium Trihydrate or ATH is widely used in construction applications as a flame-retardant filler in coatings, adhesives, and insulation materials. It releases water when exposed to heat, helping to suppress flames and improve fire resistance. Additionally, ATH enhances durability in coatings and improves material longevity.
Andricite is a finely ground synthetic anhydrous calcium sulphate used in screeds, flooring systems, and plasters. It provides a stable and efficient binding solution, improving the strength and finish of construction materials.
GGBS, also known as, Ground Granulated Blast Furnace Slag is a by-product used as a partial replacement for cement in concrete, significantly reducing carbon emissions. It improves concrete durability by reducing the likelihood of thermal cracking and enhances resistance against sulphates, chlorides, and alkali-silica reaction.
DekorFlake is a range of natural mica flakes that add a decorative metallic or shimmering effect to concrete finishes. It enhances visual appeal while maintaining the strength and durability of the material.
FireCarb is an expandable intumescent graphite that enhances fire resistance in construction materials. When exposed to heat, it expands to create a protective barrier, making it ideal for use in fire-resistant coatings and structural elements.
Gypsol is a free-flowing, self-compacting anhydrite screed binder that improves underfloor heating efficiency and provides a smooth, durable floor surface. It is a responsibly sourced alternative to traditional sand-cement screeds, offering both performance and environmental benefits.
Limestone filler is used as a mineral additive in asphalt and concrete to enhance binding properties and improve the overall strength and performance of construction materials.
MagnaDense, made from natural magnetite, is used in high-density concrete applications such as radiation shielding, underwater constructions, and tunnel linings. It enhances the structural integrity of critical infrastructure projects.
Magnetite is a finely milled material that contributes to high-density construction applications, including concrete ballast and industrial flooring, providing stability and enhanced durability.
Olivine is a magnesium iron silicate known for its high melting point and durability. It is used in refractory applications, as a flux in brick manufacturing, and in road construction for its superior wear resistance.
MicaFort, available in Muscovite and Phlogopite forms, is a high-aspect-ratio mineral that enhances coatings, concrete, and adhesives by improving flexibility, stability, and resistance to weathering.
Talc is used in construction coatings, adhesives, and polymers to enhance durability, moisture resistance, and processing efficiency. It is also utilised in ceramic and concrete applications for improved workability.
Applications of construction minerals
These minerals contribute to the construction industry in various ways:
- Structural reinforcement: GGBS, MagnaDense, and Magnetite improve concrete strength and resilience.
- Fireproofing solutions: FireCarb, ATH, and Andricite enhance fire resistance in coatings, flooring, and structural elements.
- Decorative and functional additives: DekorFlake and MicaFort enhance the appearance and longevity of construction materials.
- Responsible building materials: Gypsol and GGBS offer responsibly sourced alternatives to traditional construction components.
- Infrastructure and specialised applications: Olivine and MagnaDense contribute to tunnels, bridges, and radiation shielding solutions.
As environmental considerations and performance remain top priorities in the construction industry, the role of high-quality minerals continues to grow. At LKAB Minerals, we provide a comprehensive range of solutions designed to enhance structural integrity, improve fire resistance, and contribute to environmentally responsible building practices.
