I've not heard of a screed that would dry that quick. There is a matt you buy that you put down on the screed and tile over this.
Pretty much a damp proof membrane like what's used in basements for walls and floor, very similar concept.
there are quite a few rapid drying screeds available these days but you have to be really careful about cracking and the like. Specially in the current weather conditions. Ardex do one which is reported to be very good A35 I beleive it is called. Flexidry also do an additive. They are generally fearfully expensive though.
