When they do the bands or arches here, they glue styrafoam on then cover it with stucco, is that circled area solid concrete or grout??
The crumpled pieces are solid and feels cementitious. If you look at the red circle in the last picture, toward the left side, there is actually a rust mark, which looks like a iron wire, similar to those wire mesh we put in concrete sidewalks and driveways for reinforcement. I think these are decorative, so I don't quite get what I am looking at here.
