From January 11th to 13th, 2021, a group of 5 experts led by Professor Lv Xuewei, Deputy Dean of the College of Materials Science and Engineering, Chongqing University, including Professor Wang Chong, Director of the Department of Building Materials, and Professor Wang Zhi et al., went to Tibet Gaozheng Building Materials Co., Ltd. (hereinafter referred to as "Gaozheng Shares") for the over-all cooperation as well as other exchange activities. They participated in the establishment and unveiling of the joint Laboratory of High-Performance Concrete in Polar Region and reached a cooperation intention to jointly build the Collaborative Research Center for Polar Building Materials.

The event initiated with a unveiling ceremony for the Joint Laboratory of High-Performance Concrete in Polar Region being organized by Chongqing University and Tibet Gaozheng Commercial Concrete Co., Ltd. Solang Ouzhu, Chairman of Tibet Gaozheng Commercial Concrete Co., Ltd., and the Deputy Dean of College Materials and Engineering, Professor Lv Xuewei delivered speeches on behalf of each unit. After the establishment of the joint laboratory, the principals of both sides were appointed and a specific cooperation plan was formulated. Subsequently, Professor Wang Chong, Professor Wang Zhi, Associate Professor Jia Xingwen and Associate Professor Huang Hong gave academic reports to the management and technical staff from Gaozheng's cement and concrete business department, the topics covering "Preparation Technology and Thinking of Ultra-high Tough Cement-based Materials", "Tibetan Building Materials Industry in the 14th Five-Year Plan", "High Early Strength concrete without Maintenance in Severe Cold Environment", "Rapid Preparation and Application of Magnesium Phosphate Cement Concrete" and "Contemporary Aesthetic Application of Advanced Cement-based Materials".

Subsequently, the School of Materials Science and Engineering of Chongqing University had an exchange with Tibet Gaozheng Technology Co., Ltd.
