With the continuous improvement of people's awareness of environmental protection and resource utilization, some garbage disposal equipment has emerged to simply process and utilize construction waste. Concrete has excellent compressive resistance and is widely used in the field of construction engineering. It can also be used as a matrix to be combined with other materials to form composite materials, which are suitable for different needs. Among them, because reinforced concrete has excellent compressive resistance and tensile resistance at the same time, Widely used in the construction field. Therefore, it is a very common phenomenon that construction waste is mixed with reinforced concrete and other building materials (such as wood, aluminum) and composite materials bonded to concrete. The materials of steel bars or other building materials and concrete are different, so the recycling and treatment methods are also different. Generally, it is necessary to The steel bars or other building materials in reinforced concrete are processed separately from the concrete. However, the bonding force of concrete is very strong, making it difficult to completely separate concrete and steel bars or other building materials, and to recycle them separately.
