cement wet after pour

Hi all,

I have very little knowledge with concrete. I tried fixing some thin areas near the wall floor edge in my basement (they were damp and smelly), with some hydraulic cement. Neat stuff.. I first chiseled away the thin loose concrete stuff, then packed these areas with the cement. Anyway I have noticed that it seems to be sweating water a bit. Is this a normal part of the curing process? Also I notice that it has funny yellow colouration in large areas.

Thanks.
