Background
Along with the development of urban process in China, the discharge amount of construction waste is increased year by year, and the proportion of renewable components is also increased continuously. However, most of the construction waste is not treated at all, and is transported to suburbs or around cities for simple landfill or open-air stockpiling, which wastes not only land and resources, but also pollutes the environment. The production and utilization of recycled aggregate of construction waste is of great importance for saving resources, protecting the environment and realizing sustainable development of the construction industry, and thus the aggregate prepared from waste concrete is called recycled concrete aggregate.
When the construction waste is crushed by the crusher, the crushing degree of the construction waste with different textures is different, and if the obtained concrete aggregate is divided according to the volume size, the concrete aggregate can be roughly divided into large-sized particle aggregate, medium-sized particle aggregate and fine aggregate; and when the obtained aggregate is transported industrially, aggregates with different volume specifications are mixed together, and the mixed aggregate is unfavorable for later recovery work, so that the aggregates with different volume specifications are difficult to reasonably utilize.
