Abstract

La presente invenzione si riferisce ad un procedimento per la produzione di un conglomerato di gesso e materiale espanso granulare impermeabile, caratterizzato dalle seguenti operazioni:a) preparazione di un impasto di gesso in polvere e materiale espanso impermeabile granulare, preferibilmente polistirene, contenente un volume di 0,4 - 0,6 litri di materiale espanso per ogni litro di gesso e miscelazione a secco di detto impasto;b) introduzione rapida di detto impasto in una vasca di miscelazione munita di mezzi di agitazione contenente una quantità di acqua da 50 a 70% in peso rispetto al peso del gesso dell'impasto;c) miscelazione dell'impasto fino al raggiungimento di una viscosità non superiore a 200 centistokes;d) colaggio dell'impasto in stampi di forma e dimensioni desiderate;e) estrazione parziale degli stampi dagli stampi dei conglomerati ottenuti;f) estrazione completa e operazioni di essiccamento e di finitura.I conglomerati ottenuti, che formano anch'essi oggetto dell'invenzione, trovano particolare applicazione nella realizzazione di tramezzi divisori per costruzioni civili ed industriali.
