METHOD FOR OBTAINIG A LIGHTWEIGHT, CELLULAR CONCRETE ARTIFICIAL STONE BASED ON PUMICE STONE HAVING INTEGRATED COLOURS.

摘要

The present invention relates to the manufacture of a light stone with integrated colour based on lightweight cellular concrete pumice stones, which are stained with a liquid or powder dye soluble in water, oil, alcohol, fat, or translucent organic or inorganic solvents and with a maximum molecule size of 5 microns (um) which are introduced into the pumice stone using a pressure of between 1 kg and 20 kg/cm2 until a saturation point is reached, subsequently removing the excess and drying the pumice stone. The lightweight cellular concrete is mixed with the coloured pumice stone, white or gray cement (pozzolanic, ordinary or special), an additive for producing lightweight cellular concrete or any other system for the manufacture thereof, an oxide-based or synthetic or natural additive- based cement dye and clean water. The aforementioned compounds in proportions so as to provide the compressive strength, lightness, thermal insulation, texture, colour intensity, either to the pumice stone or to the lightweight cellular concrete mixture in order to be used, once emptied into molds and cured, as a coating for walls or floors, indoors and outdoors furniture, handicrafts, monuments, sculptures, construction elements or architectural features as they can be reinforced with steel or synthetic or natural fibers.
