Abstract

Aggregato leggero da utilizzare come inerte in una composizione di calcestruzzo, comprendente una miscela di: roccia diatomitica macinata consistente nell'85-95% in peso della miscela; un additivo fondente (A) (2.5-7.5% in peso) ed un additivo espandente (B) (1.5-10.5% in peso); detta miscela è impastata con acqua, trasformata in granuli e trattata a caldo tra 1100 e 1250°C per un periodo di tempo compreso tra 5 e 25 minuti.
