US 7,678,322 B2 · Method of producing manufactured aggregates

Abstract

The invention relates to a method of fabricating manufactured aggregates (10), characterized in that the following steps are performed: supplying a first material (12) comprising particles; supplying elements (16, 18, 20, 22) for forming a second material (14); mixing a predetermined quantity (Q12) of said first material (12) with a predetermined quantity (Q16, Q18, Q20, Q22) of each of said elements (16, 18, 20, 22) of said second material (14), so as to obtain a mortar (M12-14) made up of inclusions (12) corresponding to the first material and a matrix (14) corresponding to the second material (14); subjecting a first cure (T1) to the mortar (M12-14) for a predetermined first cure duration (t1); and crushing (C) said mortar (M12-14) to obtain manufactured aggregates (10).
