NON-STRUCTURAL CONCRETE MADE WITH POLYURETHANE PELLET WASTE FROM THE REFRIGERATORS RECYCLING PROCESS.

The invention relates to the manufacture of non-structural light concretes made with polyurethane pellet waste from the process of recycling refrigerating appliances. The manufacturing process consists of totally or partially replacing the concrete aggregates with these polyurethane pellets (PUR-pellets). The concretes are obtained by mixing cement and water with only PUR-pellet, or mixtures of PUR-pellet and other natural and/or artificial aggregates. The tests and tests carried out show that these concretes obtained by incorporation of polyurethane pellet waste (PUR-pellet) have a better thermal insulation behavior and a lower density. These concretes could be used to obtain prefabricated masonry pieces and in the execution of constructive solutions that take advantage of their benefits in the field of building.
