1. Sintering* is, I believe , a process used in the formation of
'Syncrete', but I doubt that it can be used to form a "cement"
which can be mixed with sand & water to any good purpose.

2. >(sands, water,cement...rotating mixer>) sounds too much like
earth-style Cement made from Limestone, a biological product
not found in space.

3. Will someone please post the chemistry and procedure for making
and molding/forming Syncrete and help us to make the resolution
never to use the generalized and misleading term "Concrete" in
lieu of "Syncrete" ever again!
