Abstract

Agente espandente costituito da una miscela di reflui comprendenti:a) polveri fini ottenute dalla macinazione di schiume provenienti dai forni di fusione di lingotti di alluminio primario e/o di lingotti di alluminio secondario b) residuo costituito essenzialmente da scorie saline provenienti dalla produzione di alluminio secondario.Il suddetto additivo quando addizionato ad un materiale ceramico, è in grado di provocarne l'espansione, quando il suddetto materiale ceramico raggiunge la temperatura di rammollimento.Il materiale ceramico così ottenuto dopo calcinazione risulta praticamente impermeabile all'acqua e molto resistente sia alle aggressioni chimiche che alle sollecitazioni meccaniche.
