In the paper the problem of the reuse of cubilot slag for the production of bricks usable as building materials is studied. The results of the experimental tests demonstrate that the typical measurement techniques defined in the UNI-EN guidelines to evaluate the properties, the characteristics and the possible use of the traditional ceramics, can be applied to these waste bricks. However, these measurement techniques are not sufficient to define the safety of these type of bricks. Indeed, UNI-EN guidelines for ceramics does not includes measurement devoted to define the crystallinity of the products and the interaction between the slag and the clay. In order to provide an improvement of the standard to include the waste bricks as building materials, the authors propose the introduction of X-Ray Diffraction and Thermal Analysis measurements to determine the rule of slag in the bricks production and define the specification parameters adapted to the waste materials.
