Drying out my floor slab!

[ian413]

I have just poured my floor slab in my new conservatory.
Does anyone have any idea how long it will take to dry sufficiently before I lay my new laminate floor?
It is approximatley 150mm thick and 2500mm by 4800mm.Is there a general rule of thumb or shall i leave it about 3 weeks or so?
I will be laying an underlay but this is not a damp proof membrane, just a 3mm thick layer of foam as I didn't really want to lay the laminate straight on to the concrete.

Any ides on drying time??
Thanks

laminate flooring hates excessive moisture so i should leave it a minimum of six weeks, with a window or two open for a through draft. if you can leave it longer, so be it.
