artificial coarse aggregates used in railways

The largest proportion of the primary aggregate was used to manufacture concrete in other construction uses & fills and another 2% were used for railway ballast. Both coarse aggregates (particle sizes of 20 mm to 4 mm) and fine . This 'artificial' gypsum is then recovered and sold for the manufacture of plasterboard.
