Concrete aggregate sinking-floating characteristic detection device

The utility model provides a concrete aggregate sinking-floating characteristic detection device, belongs to the technical field of concrete, and particularly relates to a high-density concrete aggregate sinking-floating characteristic detection device used for radioactivity protection. The concrete aggregate sinking-floating characteristic detection device comprises a main support (2), an upper beam (9), a lower beam (5) and steel wires (7). The upper beam (9) and the lower beam (5) are arranged in parallel inside the upper portion of the main support (2) along the horizontal direction through lug sliding sleeves (3) mounted in paired mode. The upper beam (9) is provided with a plurality of second supports (10) vertically, and the lower beam (5) is provided with a plurality of fifth supports (6) arranged horizontally in corresponding mode. The steel wires (7) sequentially penetrate through guide holes of a third support (12) on one side of the second supports (10) and fifth supports (6), and are fixedly conn
