The advantages of small-scale, decentralized cement production are being increasingly recognized. Oxymag is a Premier Magnesia magnesium oxide which conforms to the above requirements and is specially produced for making Sorel cements. Kelly I am far from an expert on the topic. Issues with Magnesium Oxide Cement Artist and Designer Michael Collins is a freeform visionary who inhabits the creative space between materials science, ecodesign and sustainable landscaping.
I have heard it is difficult to work with. Work as overcoat and also better to make the wall out of it with an organic fabric and paint it on hold it up onto a wire frame and fold the fabric over both sides and paint away....... As a side note, Portland Cement is a mix of limestone and shale solidified clay which is heated and ground to a powder also, so it is part of the same family of cements.
It doesn't dissociate into solution once the ceramic vitrification reaction occurs and from experience shows no wear or signs of deterioration after years and years.
They say it is waterproof naturally, but I have not tested this. I can see that for making roof tiles Mag cement might be ideal, as it is supposed to be waterproof and does set up quickly, so that production could proceed quite rapidly.
This magnesia cements rapid set and very high early strength has found utility as a rapid patching mortar for road and aircraft run-ways, which can typically be re-opened after about 45 minutes.

I can tell you that it is rather tricky to use, in that it sets up into a very hard material within about half an hour, so you are constantly under pressure to apply what is mixed and ready to use, as well as clean up any brushes or other tools before they become unusable.
From what I saw on youtube, is it really as easy as mixing reactive magnesium with the correct ratio of water? No oxidative reduction reaction needed as a result. Cover the panels with a layer of billboard vinyl to catch the material and keep the panels loose. It does form a a very solid material though. Having been heated in the furnace, it exhibits the same type of reaction as other minerals do in cements.
This site has some more links... Do you know anything about using magnesium cement instead of Portland cement to build a home? My method is to create a double dome with the pneumatic tech by creating two shells one foot separated from the other and vent two ways the shell and ventilate the dome through the two..... No need to fur out walls, no fiberglass, sheetrock, or paint needed.
To make a small building, take conmesh and wrap it into a cylinder; cut a door and leave at least one grid at top on top of door otherwise tie back for continuous cylinder and tension the burlap on the points of the conmesh not too tight.
