CONSTRUCTION MATERIALS WITH ANTI-FOAM AND LICHENS TREATMENT

摘要

The invention relates to the treatment of the surface of construction materials of large diffusion, used for the construction of structures, civil engineering, buildings or public houses or family housing. These materials may be based on concretes, cement fibers, terra cotta or sandstone ceramics, natural or reconstituted stones, slates, or composites. The proposed surface treatment consists of thin impacts of metal particles and eliminates the phenomenon of the appearance of mosses and lichens commonly called "greening", which happens on these materials, especially when used in areas with high humidity. The proposed treatment also leads to better aging of the treated materials.
