Ever heard of Ceramicrete, MgO cement, Magnesium cement Answered
Has anyone ever worked with MgO cement? Where can buy it in US?
MgO replaces the Ca found in portland cement. MgO cement makes a concrete that will incorporate cellulose and other organics into the crystalline structure. absorbs CO2 instead of generating it, is an order of magnitude stronger than portland, does not require wetting, and cures in minutes. So basically, you can take some burlap or old blanket and paint this stuff on, then fill the void with straw and cement and make super strong, light and thin structures.
I have looked for it locally but it does not seem to be available to consumers in the US, probably because of the lack of sheep crap which is the typical source of Mg. It is amazing stuff.
This is pretty much the only article I could find about the stuff: http://greenhomebuilding.com/articles/ceramicrete.htm
