[Greenbuilding] Redoing all floors

[Ktot (g)]

When I made that comment (no water added), I wasn't thinking about water 
before the concrete came down the chute for some reason. I was just thinking 
about someone filling a container and adding water somewhere, and no running 
water was available at the site at that point. Obviously I wasn't thinking. 
Of course I saw various concrete trucks (not the one for my slab, but ones 
for other concrete work at the house) washing out their chutes as they 
finished, so as you note, they clearly carry water.

I didn't watch the floor being poured. I don't remember why, but a lot was 
going on in the house and I had a lot of things to deal with there and 
elsewhere, but even if I had observed the pour, I wouldn't have known what 
should or should not be happening. I trusted the contractor--unfortunately 
so, in retrospect. At least my trust in all the other contractors and subs 
was well placed.

I suppose my question now on water in the concrete, is is there something I 
should try to find out from the contractor, about what may have been done 
improperly? Or should I continue focusing on the staining and sealing being 
done way too soon, before the concrete, whatever mixture, was cured? If the 
concrete mix may have contributed, I'd like to capture that information, as 
the contractor who did the defective work is going to have to pay for the 
rework.
