That's easy, none!  Lime putty is made by slaking quick lime and allowing
it to mature for a while, normally a few months. (Slaking is just adding 
water and stiring).   Hydraulic lime will set in the presence
of water but isn't made (in the UK) any more since the same can be achieved 
using modern cement.
