I don’t know the origins of the term “cement” in glue, but this “dissolves the material so it reforms as a single piece” is the principle of all cement glues, and it’s also why they are all specialty glues - you need specific chemicals to melt specific materials. It works really well. The other common term for glues that form this kind of bond is “weld”, as in plastic weld. That term makes more sense since actual welding is melting metals so they solidify as one piece. (Oh, maybe cement is like liquid stone or something - that might be where that term comes from?)
