LKAB Minerals has supplied high density MagnaDense for different bridge projects around Europe. Each of these projects unique in their design and the circumstances for placement but all in need of extra weight.
Heavy concrete for balanced bridges
The cable-stayed Samuel Beckett bridge in Dublin has a special design with heavy concrete in both pivot and bridge deck to maintain the right balance. For boats to pass, the bridge swivels open balancing on a pivot which is not situated in the middle. Therefore, the bridge needs extra weight on the short end of the construction to keep the balance perfect. In this case, the best solution for extra weight in the complete design was MagnaDense heavy concrete, as it gives more weight and requires less volume than ordinary concrete.
