[0002] As urban construction in various parts of my country is in full swing, the construction industry consumes a large amount of cement concrete every year. In 2020, cement production was 2.377 billion tons, and the amount of construction waste generated has increased accordingly; construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration, and repair. According to the composition, construction waste can be divided into slag, discarded concrete blocks, broken stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc.; At present, most of the construction waste is crushed and then separated into recycled aggregates, and the quality of the recycled concrete prepared in this way is not high. The use of carbon dioxide to strengthen the recycled aggregate can make the recycled aggregate have better physical and mechanical properties and durability, and also reduce carbon emissions; However, the existing technology of recycled aggregate carbon fixation technology has a low carbon fixation rate, and the carbon dioxide introduced is often not pure enough. The impurities in the carbon dioxide will affect the performance of the carbon fixation building materials, and then affect its quality. In order to solve this problem in the existing technology, it is often necessary to treat the carbon dioxide first, which also greatly increases the treatment cost.

[0003] Therefore, there is an urgent need for an integrated carbon-fixing building material preparation device that does not require the introduction of ultra-pure carbon dioxide. Utility Model Content
