Loose aggregate ballast for bridges
Depending on the bridge design, you can also use MagnaDense as loose heavy aggregate for:
- Foundations for anchored bridges
With a density of up to 5.1 t/m3, MagnaDense often provides the right weight and volume when limited space is available.
Bridge projects worldwide
LKAB Minerals supplied the two largest Danish bridge projects ever done with heavy loose ballast material to support the bridge’s stability. However, the use of the heavy aggregate for these two projects was different for each bridge.
- For the Great Belt bridge, the foundations anchoring the bridges need a lot of weight to remain stable.
- Our customer filled the caissons supporting the bridge deck during the construction of the Öresund bridge with LKAB Minerals’ heavy natural minerals.
A detailed case study of both of the above projects is available upon request via our sales experts.
Being part of the LKAB group with owned mines in Northern Sweden, we can promise you a secure supply of standardised heavy aggregate products.
Wherever the bridge location, we can supply MagnaDense for heavy concrete or as loose ballast with direct shipments, by rail or truck from our ports or strategic stock locations. LKAB Minerals has sales locations worldwide. On top of that, an expert sales manager is only a phone call or an email away to help you select the right mix of heavy aggregates for your next bridge project.
