There is actually an industry term for this: concrete dusting, the floor is dusting. The top layer of concrete is soft, and you can often scrape it with your fingernail.

The other day we got a call from a contractor that we have done business with in the past. One of his sub-contractors put the sewer pipe through the concrete wall in the wrong place. So he was left with a 4" sewer pipe sticking through his concrete wall that had about 8' outside also. He has to eventually put the pipe in the right place, which left him with an unused pipe sticking out...

When we see stone foundations that are painted, 92% of them are peeling, which means that only 8% are not. The reason this is happening is because there is mortar in between each stone.
