We put down 200 yards of concrete for a parking lot. I screed maybe 30 yards along the edges. I pulled concrete with the rake. Ran the bull float, ran edges, ran the power trowel, stripped, scraped and loaded steel forms. No noticeable effects on my breathing at all. No complaints from the crew.
I hit the gym last night as well, if something was affecting my breathing I'd have noticed.
