High density concrete

Both fine and coarse aggregates in concrete can be replaced by a suitable MagnaDense grade to produce concrete with a density of up to 4.0 tonnes per cubic meter.

In many civil engineering situations, for example when there is a need for stabilisation, ballasting or balancing weight, heavy weight concrete with a high density is the best solution. Producing and using heavyweight concrete with MagnaDense is possible using standard equipment.

Workability of heavy weight concrete with MagnaDense

MagnaDense is a natural aggregate manufactured from the iron oxide Magnetite. With its high specific gravity MagnaDense is used as a coarse material to produce heavyweight concrete. As a result, you will get a concrete that has more weight and your project will require less volume.

When using only MagnaDense as an aggregate, concrete with densities up to 4.0 t/m3 is achievable.  Mixing MagnaDense into concrete with other aggregates allows you to produce even concrete with densities up to 5.0 t/m3.

With the correct mix design, high-density concrete can still achieve a good workability. LKAB Minerals offers a blend to be used to produce high density self-compacting concrete.

MagnaDense acts as a “heat sink” by absorbing heat from its surroundings, storing it and releasing it slowly over a period of time. With MagnaDense used as an aggregate in concrete, this effect will mean that the heat of hydration produced during curing will be absorbed and the maximum temperature attained within the concrete will be lower than with normal aggregates. The risk of thermal cracking, which is often associated with thick sections, is therefore reduced by incorporating MagnaDense.

Applications using high density concrete

There are many applications that can benefit from heavy-weight concrete containing MagnaDense. We see the use of heavy weight concrete in different industries:
