mooncrete
n.— «After the movie, we talked about how you would build the moon base and whether you could actually create concrete using the lunar regolith. There was a specialist who designed and worked on something called mooncrete. You can use the lunar ice and use the elements in lunar regolith and actually break it down and create a concrete. That was something that was quite plausible, so I got excited.» —“Questions for Duncan Jones, Director of the Film Moon” by Erin McCarthy Popular Mechanics Apr. 14, 2009.
