摘要

Procedure for the construction of pavements, tiles and similar prefabricated cement concrete based on pebbles and boulders, characterized by a screening of pebbles or stones smoothed by water, as well as boulders and artificially transformed stones that, once assembled by sizes they are subjected to a cut in section to endow them with a flat face. Said cut is practiced by saw of a single disc or of two, when they have to form slabs with two flat faces. These pebbles and boulders are agglomerated with plaster or cement of little resistance, forming a block that is subjected to the action of any saw being made with the help of siliceous sands or other abrasives and water, boards of which, then, recover the stones separating them from their binder and obtaining marble or granite boats that will be placed together.
