Hiya folks,
I poured a 1 CY foundation for an outdoor fireplace yesterday afternoon.
Temps here are ranging from highs in the 50's to lows in the mid 20's.
After pouring, I covered it up in plastic and put around 6-8" of straw over
the top of it. This morning, the concrete is visibly wet with a bit of
standing water on it in places. I've always poured in the summer and have
seen the stuff cure pretty quickly. I suspect this is normal for these
temps but was looking for any expert opinions on this. I was planning to
start putting my CMU etc... down probably next week but at this rate, I'm
not sure I'll be able to. How long should I leave the plastic/straw in
place before working on it? Thanks much for any inputs.
Cheers,
cc
