Research Group on Magnesium-Based Cementitious Materials.
2. Brief Introduction
The Research Group on Magnesium-Based Cementitious Materials has been engaged in magnesium-related research for 30 years. Since the "Seventh Five-Year Plan" scientific initiatives, the team has completed numerous studies on the fundamental theories and engineering applications of magnesium-based materials, receiving multiple provincial, ministerial, and industry awards. The group has trained more than 20 postdoctoral researchers, Ph.D., and master's students. In recent years, the team has focused on the large-scale utilization of western salt lake magnesium resources and the development of high-value magnesium-based materials. They have completed the full cycle from fundamental research to industrialization plans, developing a series of high-value, low-cost magnesium materials and products. This work has resulted in a "magnesium salt–magnesium material–magnesium product" industrial demonstration system. The group has undertaken and completed over 10 research projects, including international cooperation projects with the Ministry of Science and Technology, the Western Action Plan of the Chinese Academy of Sciences, the "One-Three-Five" Strategic Program of Northwest Institutes, and major/critical R&D projects in Qinghai Province. They have also conducted projects funded by the National Natural Science Foundation and corporate partnerships. To date, they have established over 10 production lines and demonstration projects. The group holds more than 30 national invention patents, has published over 50 SCI papers, co-authored two monographs, and contributed to the formulation of several industry standards.

Brief CV：Weixin Zheng, Male, Ph.D., Associate Researcher, Master's Supervisor, and Head of the Magnesium Cementitious Materials Research Group. From 2010 to 2012, he worked in the R&D department of BOE Technology Group in Beijing. In 2019, he obtained his Ph.D. in Inorganic Chemistry from the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences. His research focuses on the large-scale and efficient utilization of magnesium resources from western salt lakes, with long-term efforts in theoretical innovation, technology development, and the application of magnesium-based materials. He has carried out fundamental research on enhancing the performance of magnesium cementitious materials, optimizing magnesium-based composites, designing and preparing magnesium-based products, and achieving high-value conversion of magnesium-based solid waste. He has developed a series of magnesium products or raw materials with properties such as salt resistance, lightweight insulation, energy storage, and low carbon. Dr. Zheng has led or participated in the establishment of 11 related production lines or demonstration projects. He has been a principal investigator or participant in 12 provincial, ministerial, and national key projects and has achieved five domestically leading or advanced research outcomes. Dr. Zheng has published over 40 academic papers in journals such as Ceramics International, Construction and Building Materials, and Journal of Building Engineering. He has applied for 37 patents, with 19 granted. He was recognized as a "Discipline Leader in Natural Science and Engineering Technology" of Qinghai Province in 2024 and received the province's "High-End Innovation Talent Thousand Talents Program" award in 2019. He has also been supported by the Chinese Academy of Sciences' "Western Light" program. His research achievements have earned him awards, including the Qinghai Provincial Science and Technology Progress Award and the Xining City Outstanding Academic Achievement Award in Natural Science.
