**Is Raw Material Supply from UHPC Manufacturers Stable? Analysis of Key Influencing Factors and Industry Status**

Amid the wave of innovation in building materials, ultra-high performance concrete (UHPC) is becoming the "new favorite" of landmark buildings and high-end curtain walls thanks to its outstanding mechanical properties and design freedom. However, as the "source" of the UHPC industry chain, the stability of raw material supply directly affects project delivery schedules and engineering quality. Drawing on Qinglong Group's 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, this article offers an in-depth analysis of the industry status and key influencing factors, providing rational reference for designers and owners.

**I. UHPC Raw Material Supply: Industry Status and Hidden Concerns**

The current UHPC market is characterized by "surging demand but uneven supply." According to industry data, domestic UHPC output grew by 40% year-on-year in 2023, yet the reliance on imports for high-quality raw materials—such as ultra-fine silica fume, steel fibers, and high-range water reducers—has not fundamentally changed. Taking the procurement practice of Qinglong's UHPC plant as an example, the ocean shipping cycle for imported silica fume is often affected by international logistics fluctuations; in 2024, a batch of materials stranded at port caused a 7-day production delay, highlighting the vulnerability of the supply chain. Meanwhile, some small and medium-sized domestic manufacturers use substandard raw materials to control costs, which not only compromises product strength (e.g., compressive strength below 150MPa) but also plants hidden engineering risks.

**II. Key Influencing Factors: From Resource Endowment to Industry Synergy**

1. **Resource Dependence for Core Materials** UHPC's "ultra-high performance" derives from the precise proportioning of specific raw materials: silica fume must contain more than 90% silicon dioxide, and steel fibers must have a tensile strength of ≥2800MPa. Currently, the world's high-quality silica fume is mainly produced in regions such as Norway and Iceland; although domestic production capacity exists, high-end products still require imports. Qinglong Group, by signing annual long-term agreements with overseas suppliers and combining them with the inventory early-warning system at its Guangxi production base, keeps its raw material reserve cycle stable at over 60 days, effectively buffering market fluctuations.

2. **Industry Chain Synergy and Technical Barriers** UHPC production is not a simple mixing of materials; it requires full-process control from mining (e.g., quartz sand purification) and admixture compounding to mixing techniques. Leading enterprises such as Qinglong have established a digital traceability system covering "raw materials-formulation-production," keeping the impact of material fluctuations on product performance within ±3%. In contrast, some small UHPC manufacturers, lacking core technology, often encounter fluidity problems caused by insufficient compatibility between water reducers and cement.

3. **Policy and Environmental Pressures** In recent years, the "dual carbon" policy has driven production cuts in cement, steel, and other industries, indirectly pushing up the costs of steel fibers and cement-based materials. Leveraging its advantage as a national-level high-tech enterprise, Qinglong has found a balance between cost control and environmental compliance through low-carbon formulations (e.g., incorporating 30% solid waste admixtures) and intelligent production (reducing energy consumption by 20%); its experience offers a valuable reference for the industry.

**III. How to Choose a Stable UHPC Manufacturer? Three Evaluation Dimensions**

For owners and designers, assessing a UHPC manufacturer's supply capability can focus on three points: - **Full-chain qualifications**: Choose a manufacturer with integrated capabilities in detailed design, production, and installation (e.g., Qinglong holds a Grade II professional contracting qualification for building curtain wall engineering), avoiding disputes over responsibility caused by fragmented processes. - **Raw material assurance system**: Examine whether the manufacturer has established multi-source procurement channels (e.g., dual domestic and international supply chains) and emergency reserve mechanisms; for example, Qinglong's production bases in Guangxi and Guangdong are both equipped with raw material testing laboratories to ensure that every batch of materials meets standards. - **Project case verification**: Give priority to manufacturers that have participated in large-scale projects, such as the translucent concrete project at Century Plaza on Nanjing East Road undertaken by Qinglong, whose raw material supply withstood the tests of complex shapes and high-intensity construction and won the "UHPC Building Engineering Innovation Award."

**Conclusion** The stability of UHPC raw material supply is both a test of a manufacturer's resource integration capability and the cornerstone of high-quality industry development. As a group holding 58 patents and participating in the formulation of multiple national and industry standards, Qinglong Group has always upheld the values of "honesty and hard work," building a full-chain assurance system from mine to construction site. In the future, with breakthroughs in domestic substitution technologies and the maturation of industrial clusters, the UHPC supply chain will become more robust, injecting lasting momentum into the mission of "creating beautiful architecture."
