History I / Roman Art and Engineering
Practice question · Multiple choice

Pozzolana let Roman concrete cure under water. Why did that chemistry change what Roman architecture could look like, and not merely where it could be built?

Hints
  1. Ask what sets the maximum distance between supports.
  2. What does a material that is POURED allow that one that is CUT does not?
Show the answer

B. Because it frees the interior from a column grid

Why

Cut stone dictates a post-and-lintel grid; poured concrete does not. The dome and the vaulted interior are consequences of a material that takes the shape of its mould.
