Never heard the tale of concrete or cement harming the form wood.
However, be forewarned that the coating or slag left behind may harm your sharp circ. saw blade.
I've used and seen used cleaned up form wood if necessary.
Yeah, forms lumber is reused all the time. When I was a kid they formed up basements with 1x8 lumber, then reused the lumber as rough flooring in the house. You go into the unfinished basement of many homes built in the 50s and 60s and look up and you'll see concrete on the subfloor.
My old rafters had cement on them. They were from 1952 I believe.
