Abstract: A reinforced recycled block/aggregate concrete precast column and a construction method are provided. The reinforced recycled block/aggregate concrete precast column includes several first one-bar hoops, vertical reinforcement bars, several second one-bar hoops, a flexible hinge area, and recycled block/aggregate concrete; the first one-bar hoops and second one-bar hoops are each provided with an anchor end; the first one-bar hoops and second one-bar hoops are disposed in the flexible hinge area, and only the second one-bar hoops are disposed outside the flexible hinge area; the outer edge of each first one-bar hoop is flush with the outer surface of the reinforced recycled block/aggregate concrete precast column; and the interior of the reinforced recycled block/aggregate concrete precast column is filled with the recycled block/aggregate concrete, thereby greatly increasing the recycling rate of engineering waste, reducing shedding of a concrete protective layer in the flexible hinge area of the column.
