For example, in many civil engineering situations, when there is a need for stabilisation, ballasting or balancing weight, a heavy concrete mix is the best solution. Fortunately, producing and using concrete with MagnaDenseis possible using standard equipment.See more on lkabminerals
MagnaDense, used as loose ballast or aggregate in high-density concrete, is an excellent attenuator of ionising radiation with significant reductions in HVT (half-value thickness) compared to standard concrete.
