   The usual 3 sand to one portland.  Throw in two of masons lime to make it more like a mortar and more workable if you want.  I use regular washed pit sand, or even playsand if you want.  Dry mix your ingredients and add just a little water to make it the consistancy of damp sand, like at the beach, level it out.  If you want to lay the floor and tile in one shot, sprinkle a little pure portland over the area and then sprinkle with water to make it a little creamy on top.  Lay in your tiles. Or...if they're big tiles, butter up the back of each tile with a wetter mix then lay the tile in on top of the damp mix.  Level it as you go and take a 12"x12" piece of flat three quarter ply, lay it on top of the tile and tap it with a hammer to 'set' the tile.  Or....wait a day and  use thinset on top of the cemet floor after it has cured...that's the easiest.
