Heavy weight ballast; loose or mixed in concrete

MagnaDense is a high density aggregate, used as heavy weight ballast in many applications; either as a loose ballast aggregate or incorporated into concrete.

Whether your need is for 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.

Ballasting with  MagnaDense heavy aggregate can benefit your project in many waysWhy 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 number one 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 world-wide supply

When using MagnaDense as a heavy weight ballast material under water, you also benefit from the effect called the “Archimedes Principle” as shown in image below.Using MagnaDense as ballast under water has an extra advantage as shown in the explanation for Archimedes Principle
