BEHAVIOUR OF STRUCTURES MADE WITH RECYCLED

Natural aggregates (NA) and recycled coarse aggregates (RA) were used. The NA used were lime-stone coarse gravel and river sand. The recycled aggregates came from concrete blocks used in the precast industry as support for long-span beams, with compressive strength well above 50 MPa. These concrete blocks were processed in a crushing plant ...
