Method Of Making Porous [...] Artifacts. The present invention relates to the manufacturing method, fast and at room temperature, of a new ceramic material very porous, that associates the rapid hardening cements of magnesium phosphate to release gas occurring in the dissociation of the carbonates in acidic media. The mixture post-dried may be marked previously prepared by adding water during placement in labor. The wet mass may be vented in molds, designed on surfaces and injected into cavities, hardening within a few minutes. The final product has the macro, micro and nanopores intercommunicating and thermal isolation characteristics, sound absorption, permeability and low density, having, nevertheless, a mechanical strength seldom found in products with porosity comparable. is bio and echo compatible and allows the incorporation of particles and fibers for reinforcing or property gradient, which meet environmentally sustainable applications as biomaterials, filter media, in civil construction, architecture, landscaping and agricultural wastes.
