From November 21 to 23, 2025, the 11th National Academic Conference on Commercial Mortar was successfully held in Xiamen. Co-hosted by the Building Materials Division of the Chinese Society of Silicates and Tongji University, the conference brought together industry experts, technical leaders from leading enterprises, and research scholars, with a focus on academic discussions and practical exchanges to explore innovative pathways and future development directions in the field of commercial mortar. Zhengzhou Jianwen Special Materials Technology Co., Ltd. (hereinafter referred to as “Jianwen Technology”), as a supporting organization, sent a delegation led by General Manager and Chief Technical Officer Zhang Shijie, comprising its core technical personnel, who drew significant attention at the event through their in-depth presentation of cutting-edge technological achievements.

　　Zhang Shijie is a senior engineer, serving as the General Manager and Chief Technical Officer of Zhengzhou Jianwen Special Materials Technology Co., Ltd. He concurrently holds several academic positions, including Member of the National Technical Committee for Cement Standardization and Vice Chairman of the Railway and Urban Rail Transit Materials and Engineering Technology Branch of the China Concrete and Cement Products Association. Since beginning his career, he has been engaged in the research, development, production, and management of specialty cementitious materials, such as belite–sulfoaluminate cementitious binders. He has served as the principal investigator or project leader on six research projects, including national and provincial/ministerial-level initiatives; published numerous academic papers; obtained 12 authorized invention and utility model patents; and participated in the drafting of 11 national, industry, and association standards. His research achievements have been extensively and successfully applied to key national infrastructure projects in China, such as high-speed railways and cross-sea bridges. He has received honors including “Outstanding Party Affairs Worker of Xinmi City” and the “Innovation Award in the First National UHPC Custom Design Competition.”

　　At this conference, General Manager Zhang Shijie delivered an in-depth presentation titled “Research on the Application of Belite Sulfoaluminate Cementitious Materials in Mortars.” The findings of this research have been included in the Proceedings of the 10th National Academic Conference on Commercial Mortars, focusing on the technological breakthroughs and practical value of Jianwen Technology’s core product—belite sulfoaluminate cementitious materials. This product was developed through prolonged and arduous efforts by our company’s technical team, building upon the original invention of the Tianjin Cement Industry Design Institute and benefiting from the strong support and guidance of the Institute and other renowned industry experts. It integrates the superior properties of sulfoaluminate cements and various other cementitious materials, achieving well-balanced performance across early, mid, and late stages. After hydration, the resulting products exhibit a highly dense microstructure, characterized by low drying shrinkage, slight expansion, rapid setting and hardening, high early strength, and sustained strength gain with age. These properties make it particularly suitable for applications such as floor leveling mortars, high-strength repair materials, high-strength non-shrink grouts, injection grouts, and UHPC-based products. Currently, the primary application areas for this product include self-leveling mortars, sculpted mortars, terrazzo mortars, high-strength repair materials, high-strength non-shrink grouts, grouting and reinforcement materials, waterproofing and leak-stopping materials, as well as GRC and UHPC products.

　　Owing to its outstanding performance, this material is well-suited to a wide range of application scenarios, making it the ideal choice for numerous specialized engineering fields:

　　Flooring mortars, such as cement-based self-leveling mortars, can effectively address issues like dimensional changes and bond strength with the underlying concrete substrate.

　　For terrazzo and sculpted mortars, belite sulphoaluminate cementitious agents offer advantages such as early strength, rapid hardening, low shrinkage, and corrosion resistance, thereby effectively addressing the shrinkage issues inherent in terrazzo applications and the challenges of achieving early strength and corrosion resistance in sculpted mortar applications.

　　Airport runway and highway rapid-repair mortar can achieve normal service performance within two hours. Road concrete formulated with belite–sulfoaluminate cementitious material blended with an early-strength admixture requires no special curing. Moreover, this cementitious material exhibits strong bonding, high workability, rapid setting, and slight expansion, effectively mitigating concrete shrinkage; its superior impermeability also prevents surface water from infiltrating and damaging the road base. Consequently, it is an ideal binding material for emergency road repairs, grouting reinforcement, wind-turbine foundation grouting, bridge bearing grouting, and other similar applications.

　　It can meet the requirements for rapid setting and early strength in other civil engineering applications. Due to its outstanding properties—high early strength, excellent resistance to permeation, superior freeze–thaw durability, good long-term stability, corrosion resistance, short setting time, low alkalinity, and low free expansion rate—belite sulphoaluminate cementitious materials are widely used in specialized engineering fields. They are perfectly suited for a variety of applications, including floor screeds and high-strength repair materials, and align closely with the construction industry’s trend toward green and low-carbon development.

　　This conference serves as a vital platform for Jianwen Technology to showcase its technological prowess and champion innovative ideas, while also presenting a key opportunity for the company to deepen collaboration with industry peers and jointly pursue sustainable growth. Moving forward, Jianwen Technology will remain steadfastly committed to R&D and breakthrough innovation in the field of specialty cementitious materials, delivering higher-quality products and more specialized solutions to drive high-quality development in the construction industry and inject stronger core momentum into the green and high-performance transformation of the ready-mixed mortar sector.
