	<htmltext>...sounds like a great choice as resources to use. As Sand is basically silicon and readily available, magnesium is also <a href="http://education.jlab.org/itselemental/ele012.html" title="jlab.org" rel="nofollow">the 7th most abundant</a> [jlab.org] in th earths crust.

It seems like this thing could go a long way towards very cheap mass production of all sorts of solid things very cheaply.
There is also the <a href="http://reprap.org/wiki/Main\_Page" title="reprap.org" rel="nofollow">RepRap project</a> [reprap.org] but they use plastics which I'm afraid are quite expensive as resource, although
they kind of target a different area.

I'm excited by this, I've been following these ideas for a while and it seems to be going somewhere, I guess we're getting closer to general purpose building machines.</htmltext>

	<htmltext>There are several different formulations of magnesium-based cements, so it's hard to say what the properties of this material would be- and concrete is a complex material where small tweaks in composition can make for big alterations in attributes.  I found this <a href="http://www.d-shape.com/d\_shape\_presentation.pdf" title="d-shape.com">brochure from D\_Shape</a> [d-shape.com] (PDF) that underneath the dramatic vision-pitching gets at more of the specifics.  From the description of the material, "The stone is very similar to marble," and the description of what comes out of the nozzles as "a bicomponent liquid/solid inorganic binder," it sounds like a form of magnesium oxychloride, aka Sorel cement.  Sorel cement is prepared by mixing solid magnesia (MgO) with magnesium chloride brine.  It goes on to mention the possibility of adding
"reinforcing fibres selected from the group comprised of glass fibres, carbon fibres, nylon fibres."
<br> <br>
Magnesium-based cements can be superior to their calcium silicate (Portland cement-like) counterparts in terms of strength, and they set very quickly, but the traditional issue they have had is that they are more susceptible to water erosion (the cured cement is more water soluble than Portland cement), and so they've been more popular for quick-patch type work rather than large-scale construction.  Modern advances in its composition are improving its water resistance, however, and notably, water erosion would not be much of a problem on the moon.</htmltext>

But doesn't it follow that, no matter what material they use, they won't exactly want to be putting new holes into their space house?</htmltext>

	<htmltext>I always thought that we need robots to build a moonbase before we bother sending people up there again. Here's one robot that might help get the job done. Then again, it seems like a major piece of hardware that will be difficult to transport. But the idea of making stone from dust is a good one. Maybe we should half-inflate a giant balloon so its top is dome-shaped, cover it with layers of moon dirt which would be hardened with this magnesium fixative. Once the stone is thick enough, the dome will be self-supporting and a good radiation shield. The whole process might be done by a single remote-controlled backhoe with a spray-nozzle. This is the kind of cool shit that NASA should be doing.</htmltext>
