The use of construction waste and industrial solid waste to prepare green and sustainable building materials is of far-reaching significance. This approach not only mitigates the accumulation of waste and reduces environmental impact, but also transforms waste into a valuable resource, thereby offering a sustainable avenue for building materials. From an environmental and energy-saving, it reduces the demand for fresh resources and thus the pressure on the natural environment. Furthermore, it contributes to a reduction in carbon emissions caused by waste disposal, aligning with the goal of carbon neutrality.

The goal of this Research Topic is to focus on the development of efficient and eco-friendly sustainable building materials from recycled cement/concrete and recycled industrial wastes. Preparation processes and technologies for the large-scale use of construction waste and industrial solid waste to produce green building materials should be developed. At the same time, research should also focus on how to improve the performance of products and reduce production costs to enhance the competitiveness of these eco-friendly materials.

Within the scope of this Research Topic, the feasibility of this preparation method should be fully evaluated from diverse perspectives. This encompasses the investigation of the physical, chemical and mechanical properties of materials, examination of energy consumption and emissions during preparation, and exploration of their application prospects and potential in the construction industry. Additionally, studies of relevant policies, regulations and economic impacts are necessary to support large-scale replication and adoption.

Key themes for this Research Topic include:
• Recycled concrete;
• Recycled cement;
• Sustainable building materials derived from industrial wastes;
• Preparation methods;
• Evaluation of Physical, chemical and mechanical properties of recycled construction materials;
• Evaluation of energy consumption and emissions during preparation;
• Policies, regulations and economic impacts.
