(OP)
is it about the normal force between the concrete and steel? and what the usual size of the strands?

For 7-wire strand, 1/2" (12.7mm) is more common in building structures and 0.6" (15.2mm) is more common in bridges, at least it is in the USA and Australia.
In the UK, the precast industry used to use (and some still do) 3-wire strands for prestressed planks.
