Another sustainable building material – Ferrock.

This is another concrete alternative. ?I think it’s great people are still creating and innovating. Although concrete is cheap and free to use, it is not good for the environment.

This Ferrock actively traps carbon in the form of steel. I think it’s also great because it has that great rusty look.

Did you know that concrete is the second most used substance in the world after water? It also accounts for 10% of the earth’s carbon emissions. This is why we need fast solutions to the earth’s fascination with concrete. As well as this Ferrock also has a negative carbon usage. It actually locks in existing carbon. We think this is super cool.

Wondering how ferrock concrete is made?

Ferrock how much co2 is absorbed? Approximately 95% of Ferrock is made from recycled products. This is an amazing figure and one to be strived for in this current climate. As well as this concrete is a very wasteful building material, it is simply so widespread because it is cheap, quick and easy.

Who invented Ferrock?

David Stone (Ph.D.) Invented this material. At the university of Arizona he discovered this material after experimenting with iron dust studying environmental chemistry. It retains it rock like properties when poured

How to buy ferrock?

Wondering where to buy ferrock? Ferrock has not really taken off could partially do with the cost of the substance. The cost of iron dust is still quite high because iron is quite a precious metal so this could be why ferrock has not entirely taken off yet. Perhaps in the future it will take off. You can make it yourself or even buy online.

Wondering what Ferrock is made from?

  • It is created from excess steel dust which would normally be trashed.
  • Silica from ground up glass
  • Which is poured into a mould. Upon reaction with the air and carbon dioxide; iron carbonate is formed. This binds the carbon dioxide in with ferrock, trapping it into the blocks. Thus actually making this material carbon neutral or carbon negative.

How to make Ferrock

You will need:

  • iron dust 60%
  • fly ash 20%
  • Metakoalin 12%
  • limestone 8%

Mix all of these ingredients together and there you have it something that is strong as concrete with a lot less of the guilt.  Did you know that for every ton of cement that is produced, 8 tonnes of carbon dioxide are released into the atmosphere?

That to me is incredibly alarming.
