| Abstract |
In recent years, as the concepts of "zero waste" and "low carbon" gradually become hot topics, the unparalleled generation of construction and demolition (C&D) waste that poses a significant obstacle to the sustainable development of the built environment has attracted a lot of attention from researchers. Whether the studies on the combination of C&D waste recycling and carbon dioxide (CO2) utilization provide a feasible way to transform the two goals is worthy of discussion. Thus, this study targeted to review previous research to describe the research trend and clear the positive and negative sides of CO2 employment in recycled construction materials. It shows that after the utilization of CO2 in the recycling process, the performance of recycled construction materials can be improved in many aspects under a proper carbonation reaction. Besides, many studies have proved that the carbonation of C&D waste is a recycling method and effective carbon capture and storage tool to accelerate the sequestration of CO2. It should be noted that although the current technical research on the carbonation of recycled construction materials has become mature and feasible, the use of carbonation has also contributed to apparent negative effects. On the one hand, carbonation is only positive for plain concrete, and the reinforced steel structure can be corroded by acid. On the other hand, the high equipment requirements used in the carbonation process could lead to increased economic costs. These reasons collectively hinder the application of carbonation technology in practical construction projects. The United Nations Sustainable Development Goals (SDGs) and carbon-neutral goals of countries have put forward higher and more explicit requirements for global sustainable development. Theoretically, the carbonation of recycled construction materials is one of the viable paths for sustainability. However, technical difficulties such as energy consumption, economic cost, and corrosion for widespread applications need to be overcome. |
