Staining/Discoloration on Recently Poured Slab on Grade
(OP)
I have an interior slab on grade that is showing staining and discoloration. In some places it looks as though mud was smeared on it. It was recently cleaned, so it is not dirty. It was poured about 3 months ago. The weather at the time was slightly below freezing, however the roof was on the building and they where pumping heat in through the two doors so it was pretty warm in there. It was finished with a walk behind power driven steel trowel after it appeared as though the bleed water had come out. After finishing, a combination curing/sealing compound was applied. Any ideas as to what caused this staining and discoloration? Thanks!

for a slab on grade, I'm sure its nothing to worry about.

Added: Funny how you notice these things after you post. Discolouration can occur if there is a non-uniform surface of bleed water left on the slab.
