Ferrock concrete is made with mostly recycled materials


“David Stone is the brains behind a new patented concrete technology known as Ferrock, based on iron carbonate and incorporating largely recycled materials to produce (around 95%)! It’s showing promising signs as an alternative to concrete and a far greener building material.

The name Ferrock is a reflection of its composition – largely iron-rich ferrous rock. It’s actually created from waste steel dust which is normally discarded from industrial processes and silica from ground up glass. The iron within the steel dust reacts with C02 and rusts to form iron carbonate. It’s this that is fused into the matrix of Ferrock and, like concrete, after it’s dried, it cannot be melted back into a liquid form but retains its hard, rock-like qualities.

What are the advantages?
Compared to Portland cement (made from chalk and clay and resembling Portland stone in color), which is one of the leading types in use throughout the world today, Ferrock is actually five times stronger. It can withstand more compression before breaking and is far more flexible, meaning it could potentially resist the earth movements caused by seismic activity or industrial processes. One of the unique properties of Ferrock is that it becomes even stronger in salt water environments, making it ideal for marine-based construction projects. And rather than emitting large amounts of C02 as it dries, Ferrock actually absorbs and binds it! This results in a carbon-negative process that actually helps to trap greenhouse gases.”

  1. of course the first thing people do is patent everything sigh.
    That means that only the relatively wealthy will be able to access it so really, what’s the point? It looks nice, sort of like gingerbread, but there’s really a question whether this will ever apply to those of us scrounging to build a house.

    • The main point is to raise awareness of alternate/greener concretes that are coming out. Some are already available in certain areas. More awareness will hopefully translate to greater demand.

  2. Ugh. This is just like all those other wonder materials. How can I make it? Where can I get it? Short answer, you can’t. It’s not ready for market, the company isn’t marketing it in the US, the precursors might cost a corporation pennies a ton but a person can’t have it at all.
