Solutions for coastal and marine structures

Coastal and erosion protection
By using high density concrete such as MagnaDense producing rubble mound breakwaters, a reduction of the required edge length of cubes is achieved meaning that the volume of the cube can be significantly reduced.

LKAB Minerals attended ICE 2013 to highlight solutions for the challenges created from sea to shore focussing on coastal protection.

Over 40 civil engineering and manufacturing companies congregated in Edinburgh during the 18th to the 20th September to exhibit to 400 attendees, making it the biggest conference to date at the EICC venue. As demonstrated during the event, contractors and designers within the coastal protection area meet many challenging situations. Objectives are often to achieve sustainable constructions with high esthetical values and materials that withstand long-term exposure to impact from environment and users.

Benefits of designing coastal protection using MagnaDense

LKAB Minerals' MagnaDense is a high-grade aggregate manufactured from the natural iron oxide Magnetite. Mined and processed at our own group resources in the North of Sweden, its high density and inert properties provide an effective solution when stability and corrosion prevention is required in coastal defences.

For instance, in the design of rubble mound breakwaters used for coastal protection, the stability of armour layers is one of the most important aspects. By using high density concrete such as MagnaDense in the layers, a reduction of the required edge length of cubes can be achieved meaning that the volume of the cube can be significantly reduced. This can lead to a reduction in cost when transporting the breakwaters from the manufacturing facility to the project site. With MagnaDense it is possible to make high density concrete with densities up to 3.9 t/m3. Therefore it is also used in (smaller) elements to cover and protect riverbanks. The use of MagnaDense increases stability without changing the shape and the size of the element.

Coastal and erosion protection

Representatives from our technical and sales team were on hand to illustrate the use of MagnaDense as well as networking with the international community. As a company that prides itself in producing innovative solutions, events such as this provide a fundamental opportunity to increase our knowledge and promote our products which offer value and relevance. In addition to the busy technical exhibition over 200 abstracts were submitted from across the globe, including 130 peer-reviewed international paper presentations, covering the latest developments in coastal and marine engineering.

LKAB Minerals’ Denise Roberts, Business Development Manager for Offshore, attended the conference and commented, "Coastal protection is a very interesting area for our company and this event was particularly worthwhile for us. Many good contacts were made and we are looking forward to following them up and building partnerships."

LKAB Minerals is committed to attending relevant industry events such as this throughout next year with the aim of promoting MagnaDense’s key qualities which makes it an ideal heavyweight aggregate to use in the Civil Engineering and Offshore industry.
