MagnaDense concrete for dolphin mooring quay

Different grades of MagnaDense
MagnaDense was used in high density concrete at the Dolphin Mooring Quay

LKAB Minerals supplied MagnaDense for the concrete construction of a new mooring quay at the Port of Tyne(UK).

As the previous quay failed due to damage a new dolphin mooring needed to be constructed for the Northern English Port of Tyne next to Newcastle. This very busy harbour not only gets a lot of loading vessels but it is also a well-used harbour for ferry boats.

Mixing the right heavyweight concrete

To make sure that this structure is strong enough to withstand the forces of the ships mooring the concrete must be very solid. MagnaDense concrete was chosen for two reasons; firstly because it is economically much more interesting than piling and secondly MagnaDense gives concrete its high density.

“Sherburn Stone successfully produced and supplied two pours of pumped heavyweight concrete, each 125 m3, for Southbay Civils in the Port of Tyne. This was achieved by good preparation before supply.” said Peter Bell, General and Technical Manager for Sherburn Stone.

Natural mineral with high density

MagnaDense is made from the natural mineral Magnetite and mined in our own mines in Sweden. It is used in many offshore and civil engineering projects where weight is needed but volume cannot be increased. MagnaDense is used as loose ballast or, as in this case, mixed into concrete. Our natural mineral has a CE certification and is approved according to EN12620 for use as an aggregate in concrete. MagnaDense concrete has a long history of use as a construction material and apart from its weight, remains flowable and can be placed by skip or pump.

LKAB Minerals has over half a century of experience in supplying MagnaDense for high density concrete applications. We help our customers to select the right mix of grades for their specific projects.
