Ballast material

Whether your need is for heavy weight to balance a bridge, to keep a gravity-based structure in place, to make a counterweight for heavy vehicles or any other ballast project, you’ll need a high density material to get the right weight for your design.

Why MagnaDense is preferred as heavy weight ballast

Depending upon your application MagnaDense can be used as a loose ballast or mixed into heavy concrete. The main reason for choosing our product is because of its weight, but there are many additional reasons to opt for the LKAB Minerals heavy aggregate. We have listed the important benefits of our natural high density material below:

  • Weight; density of up to 5.1 t/m3
  • Less volume; in comparison with other aggregates or standard concrete
  • Inertness; does not react or corrode when in prolonged contact with seawater
  • Recyclable; sustainable for both the environment and your assets
  • Reduces risk of cracking; when mixed into concrete it aids in reducing cracking risk
  • Quality; always the same specification for each grade
  • Availability; year-round worldwide supply
  • Archimedes principle benefit; relative more weight when used under water (see picture to the right)
Which benefit is most important for you and your project? Tell us in a one-on-one conversation with a regional sales manager who can help you select the right grades. Contact details can be found on this page.
