  • The properties of recycled precast concrete hollow core

    Waste concrete from prestressed precast hollow cored floor units has been recycled for use as replacement aggregate in concrete (RCA). Waste concrete blocks were crushed to −14 mm using cone, impact and jaw crushers. All produced acceptable physical and mechanical properties, although the impact crusher was best suited in most cases.
