Concrete never had magnetic properties until now. This is actually easy by just replacing gravel and sand by coarse and fine magnetic fillers merging the worlds of construction and electromagnetism.

 
 

 

High permeability (up to 70) opening up a broad range of electromagnetic applications.

No pressing process needed, offering many possibilities for cost-leading and size-unlimited parts.

LOW POROSITY (3.5%)

 

LONG LIFETIME

FAST HARDENING

 

LOW POWER LOSSES

SELF-COMPACTING

 

HIGH CORROSION RESISTANCE

 

Uniquely suitable for mechanically rugged inductive components with high environmental stability.

They are sold as premixed concrete requiring only the addition of the exact amount of water.


LOW CO2 FOOTPRINT

Our concrete consists of 87 % magnetisable aggregates, which is a waste product arising from the manufacturing of ceramic ferrites and the recycling of electronic scrap.

This material as well as the cement are provided by local suppliers thereby generating a very low CO2 footprint.

SOFT FERRITE SCRAP

Additionally we save energy during the processing of the concrete by:

  • Using as much as possible coarse aggregates (low crushing energy)

  • Processing of self-compacting concrete (no energy for densification)

  • Requires no heat treatment or sintering energy

Magment does not contain any ingredients exceeding concentrations dangerous to health according to legal regulations (like RoHS - 2011/65/EU).

Our concrete does not behave magnetically on the basis of rare elements. Any ingredients are almost unlimited available. Iron, Manganese, Calcium, Silicon and Oxygen belong to the 12 most naturally-occurring elements in the Earth’s crust.

Chemical element abundance analysis for MAGMENT materials clearly shows the advantage of inductive charging to minimize lithium nickel cobalt batteries

ADDING WATER SETS OFF A CHEMICAL REACTION

by Mark Miodownik

...If you now add water to this powder it sucks it up with ease and darkens. But instead of forming a slushy mud, which is what happens if you add water to most powdered rock, a series of chemical reactions takes place to form a gel. Gels are semisolid and wobbly types of matter - the jelly served at children’s parties is a gel, and so too is a lot of toothpaste. It doesn’t slosh around like a liquid because it has an internal skeleton that prevents the liquid moving. In the case of jelly this is created by the gelatin. In the case of cement, the skeleton is made up of calcium silicate hydrate fibrils, which are crystal-like entities that grow from the calcium and silicate molecules, now dissolved in the water, in a way that appears almost organic. So the gel that forms inside cement is constantly changing as the solid internal skeleton grows and further chemical reactions take place.

...As with any chemical reaction, if you get the ratio of the ingredients wrong, then you get a mess. In the case of concrete, if you add too much water there won’t be enough calcium silicate from the cement powder to react with, and so water will be left over within the structure, which makes it weak.
Similarly, if you add too little water there will be unreacted cement left over, which again weakens the structure. It is usually human error of this sort that proves the undoing of concrete. Such poor concrete can go undiscovered but then lead to catastrophe many years after the builders have departed.
