| Summary: | The artificial aggregates represent the solution for solving the difficult problem of industrial waste disposal and, in addition, they can substitute natural aggregates. Concrete results with simple tools and materials can be produced, such as brick studying its properties and applications with a careful experimentation with productive character. As a consequence, the high environmental quality, if pursued with care for technological innovation, is not a constraint, but a real economic opportunity that increases efficiency of natural resources, energy and materials, for obtaining a final product with high performances
