Are there any native english speaking engineers (or someone otherwise
into this topic) on this list?
1. I would like to know (besides what wikipedia:en states), whether
gravel pits are comprised in "quarry". I'm quite sure that "rubble" is
inside "quarry", but am not sure for "gravel".
2. What about sand and clay. Do they come from "quarries"?
