Eco-friendly Substitute for Cement
Posted by freedomforall 9 years, 4 months ago to Technology
" Annually, 4-billion metric tons of cement is made worldwide for use in concrete, and for every ton of cement manufactured, approximately one ton of carbon dioxide is released into the atmosphere. Conversely Ferrock™ only hardens when exposed to high concentrations of carbon dioxide, which is absorbed and trapped, making it a carbon negative material. This greenhouse gas diffuses into the wet mixture and reacts with the iron, creating iron carbonate and becoming part of the material’s mineral matrix."
Approximately 300,000 years ago, in Sibudu, (near bottom of Africa), the commercial production of ochre began. What most folks do not realize is that ochre combined with pine sap forms a two-part epoxy (used for attaching hafts to spear and arrow points). If I recall correctly, this was due to the ferrous ions in the red ochre. So - after 300,000 years, we have reinvented the process.

I looked up and read about the aidomes after they were mentioned. I am NOT expecting the developers of those structures to have an opinion of this just-developed cement. I do think that 'improved strength and flexibility' would be an advantage for that type of construction.

So remember, comrade citizens, remember to buy only Eco-Freindly Cement. It is only sold by fine crony stores.
