Any contractor/handyman dads out there?

Just a quick question. We had some plumbing done, and part of the floor was torn up to re-route pipes. when the concrete was poured back, it took a while to cure, but finally did, however there is this portion (pic below) that seems to be taking longer, or has another issue maybe? We have radiant heating below the floor, so I was afraid maybe this was the result of a leak, but there isn't any other water coming up from any of the cracks or edges at all, so I'm doubting that's it. Maybe this portion was just thinner so it's taking longer?

Does that look normal? The outer gray line seems to be spreading outward, but becoming lighter also...

Probably nothing, I just don't know about this stuff... Thanks guys.

I see your problem, there's a Yankee Jersey buried there.

Concrete doesn't take very long for the visible parts to cure. I'm not sure how think they poured there, but the visible parts should all cure about the same rate. A slab 6" think will continue to cure for 30 days or more, depending on humidity. The thicker it is, the longer it takes.

It's tough to tell from your picture, but if the concrete hasn't visibly cured after 10-12 hours, I'm afraid you probably have a problem. Whether that problem is a leak or something wrong with the concrete, I can't tell.
