What is the sure way to set tiles without damaging it using conventional tools?

There are several ways in the countries of the world and we are in Iraq we furnishings light layer of sand on the ground and then cover it with a layer of cement-free gravel so as not to break the tile and then after two or three days we mix cement white with a large amount of water for industry mix light Tmlae openings between the tiles Of course, if colorful tiles add color as desired with this mixture, or not necessarily, each according to his taste and all this process for builders concrete course

I hope the response would be useful
