The parent concrete used in this work contained 375 kg/m 3 cement, 180 kg/m 3 water (i.e., w/c of 0.48), and sand-to-aggregate ratio of 0.55 . A laboratory jaw crusher was used to produce aggregates having 0 to 20 mm particle sizes. The RFA is then obtained by sieving the aggregates using a 4.75-mm sieve and collecting the 0/4.75 mm fraction.

The precise and powerful roll pressure unit generates linear loads from 5 to 120 N/mm (P-rolls 90 to 120 N/mm), significantly wider for both low and high roll pressure than traditional mills. Products can be processed in a low roll pressure range (5 to 25 N/mm) for better repeatability.

aggregate by dry weight proportions were 1 :3 and 1 :4. RA com­ ing from treatment plants was sieved in the laboratory, eliminating material retained on the 4 mm sieve and material passed through 0.063 mm sieve, because of poorer characteristics of aggregates of this fraction. Preparation of ali mixes was performed using the same tech­
