Shi Caijun pointed out that the preparation of low/negative carbon building materials and products by carbon mineralization involves complex physical and chemical processes, and fine regulation can significantly improve performance. The capture and storage of carbon requires considerable cost, and the direct use of tail gas for carbon mineralization is the most economical and effective way of carbon utilization. The durability and structural properties of carbon-mineralized products need to be studied to expand their applications.

On March 13, the 14th China Cement Industry Summit and TOP100 Award Ceremony Technology Special Event sponsored by China Cement Network was held grandly. Shi Caijun, the chief professor of Hunan University, a national specialist, made a keynote report on "Mineralization and Utilization of Carbon Emissions in Cement Industry".

Shi Caijun introduced the mineralization and utilization of carbon emissions in cement industry from four aspects: background, development history of CO2 mineralized cementitious materials, preparation of low/negative carbon building materials and products by CO2 mineralization of cement kiln tail gas, conclusion and prospect.

The Measures for the Implementation of Capacity Replacement in the Cement and Glass Industry (2024 edition) shall promote the unification of the registered capacity and the actual capacity. For the compliance production lines whose actual capacity is greater than registered capacity, it is proposed that the difference in capacity can be made up in accordance with these Measures and the relevant procedures such as filing, environmental assessment and energy assessment can be improved. But the reality is that the actual production of enterprises is still exceeding the record capacity.
