摘要

China is a significant global producer of cement and a major contributor to carbon dioxide emissions within the building materials industry. However, in the context of the prevailing climate change challenges, the cement industry has prioritized energy conservation and carbon reduction as its primary objectives. Solid waste cementing material can be used as an alternative to reduce the emissions and heat generated in the cement industry, thus contributing to the collaborative treatment of solid waste and environmental control. This paper introduces the all-solid waste material as a potential replacement for cement. This material only requires grinding without sintering, its raw materials are all-industrial solid waste, and its production process does not emit any toxic and harmful gases, thus contributing to carbon emission reduction. This material also shows compressive properties and its solidification performance is better than that of standard cement and metals (including lead, cadmium, arsenic, and chromium) and satisfies the drinking water standard (GB 5749-2022). Using the carbon emission accounting method, this study highlights the low-carbon and energy saving properties of the all-solid waste material. This material is also environmentally friendly given its low energy consumption and CO2 emissions, thus providing an avenue for further research on cement alternatives.
