Here is an
image of the concrete curing process, in regards to two different forms of curing concrete. One is precast (pic on left) which is mildly steel reinforced, and the second is prestressed (pic on right). Prestressed concrete is achieved by stretching high strength steel cables (strands) through the concrete. This does not allow the concrete to bend, break, or brittle during curing. Precast concrete is unable to recover after/IF too much pressure is applied. If you're talking about discoloration in regards to the blue scaffolding and the brown stuff on it, that should be dust cause it can't be anything else at a construction site.
