concrete

It'll be firm enough to stand or walk on but will still be very green and so will be fragile and easily broken at the edges if they are unsupported.
What are you intending to do with or on this concrete?
I seem to recall some rule of thumb that says something like a month an inch before laying a timber floor on top. You'll have a huge amount of water in that slab that with the DPC in place can only escape upwards.
There's a poster on here called woodulike (or something similiar) who seems to be something of an engineered floor guru, I think it's his living, hopefully he may give a definate answer.

the answers above relate to how long you should leave the concrete until you could tile on it, which you are not going to do. However the slab is going to continue tb shed this water whatever happens and I'm not sure what the result would be if you put impervious insualtion on top followed by a screed before it was dry.
By the way, when you lay the screed, you will also have a long drying-time. The different "rules of thumb" are :
1) One day per mm
2) One week per cm
3)One month per inch
Bit of variation there as you can see.
By the way are you really pushed for time to do this, or just surprised at the length of drying-time ?

A site agent I have worked with in the past had an oak floor laid on top of green screed a couple of years ago, time constraints and a rush to get the job done but ultimately the boards ended up looking like some sort of corrugated floor and had to all be ripped up 
still every cloud and all that- there were several oak fuelled warm houses that winter
