<p>Process for manufacturing a composition of cement made of waste or virgin materials of various kind, adapted to be used with the function of material having good thermal conductivity, particularly in the building industry, as self-levelling screed for covering the heating panels to be applied on to the floors of traditional type. Process utilizing component materials from which the metallic materials have been eliminated, and the aluminium has been eliminated or reduced up to a percentage lower than 1% by weight, by means of a specific de-aluminizing process. Also a composition of cement obtained with such manufacturing process is described.</p> |
