Can You Produce UHPC Yourself? Feasibility, Key Technical Points, and Considerations for Homemade UHPC

Expertise forges quality. The exceptional performance of UHPC never relies on the luck of "DIY"; it stems from full-chain technical accumulation and the rigor of standardized production.

In recent years, with the widespread application of UHPC (Ultra-High Performance Concrete) in architectural decoration, many industry professionals and enthusiasts have begun exploring the possibility of "homemade UHPC." As an industry technical team with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group believes it is necessary to analyze the feasibility boundaries of homemade UHPC from a professional perspective and provide a rational reference for the industry.

### I. The Technical Barriers of Homemade UHPC: From Material Ratios to the Risk of Performance Failure

UHPC is not a simple enhancement of ordinary concrete; its core lies in technologies such as ultra-fine particle gradation, three-dimensional distribution of steel fibers, and optimization of the interfacial transition zone. Professional production requires precise control of the purity of raw materials such as silica fume and ultra-fine quartz sand (e.g., SiO₂ content ≥92%), as well as the aspect ratio of steel fibers (typically 13-20mm) and volume fraction (2-5%). In homemade production, without professional gradation design and homogeneous mixing equipment, problems such as fiber clumping and excessive strength dispersion can easily occur, causing significant degradation of compressive strength (standard requirement ≥150MPa) and flexural strength (≥25MPa). Experimental data show that non-standardly produced UHPC components have durability indicators more than 40% lower than industrial products, directly affecting engineering safety.

### II. The Core Barriers to Mass Production: Systematic Integration of Equipment and Processes

The professional UHPC production line at Qinglong Group's production base in Nanning, Guangxi, covers full-process technologies including vacuum mixing, steam curing, and CNC forming. Take the curing stage as an example: industrial-grade autoclaved curing requires strict control of the temperature gradient (heating rate ≤20℃/h) and humidity environment (≥95%)—key steps that are difficult to achieve in a homemade setting. In addition, the General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC), which Qinglong participated in formulating, explicitly requires that products pass rigorous tests such as 200 freeze-thaw cycles and 5,000 hours of weather resistance, all of which must be completed with professional laboratories and testing equipment. For designers and owners, choosing a UHPC manufacturer with full-chain capabilities in "detailed design - manufacturing - construction and installation - after-sales maintenance" is the core prerequisite for ensuring project quality.

### III. The Rational Choice of Industry Practice: The Value of Professional Customization and Full-Cycle Service

In the Century Plaza renovation project on Nanjing East Road, Qinglong used light-transmitting UHPC to achieve a design effect of "crystal-clear by day, radiant by night," backed by the systematic support of parametric design (Rhino+Grasshopper), BIM technology application, and modular installation. The realization of such complex projects is far beyond the reach of simple homemade production. For professional clients such as real estate developers and architectural design institutes, Qinglong provides not only material products but also full-cycle solutions from scheme optimization to cost control—for example, in commercial complex projects, the GRC/UHPC composite curtain wall system delivers comprehensive benefits of a 30% reduction in dead weight and a 25% shorter construction period.

### Conclusion: Let Professionalism Remain Professional—The Right Way to Apply UHPC

The technical appeal of UHPC lies in its ultimate performance breakthrough, and such breakthroughs require the technical accumulation of professional teams and the safeguard of standardized production. Whether it is the irregular curtain walls of grand theaters or the artistic components of landscape gardens, only by choosing a UHPC manufacturer like Qinglong—with a national-level R&D center and participation in industry standard formulation—can the technical value of the material be truly realized. In the field of architectural decoration materials, "professionalism" has never been a gimmick, but a solemn commitment to project safety, design effects, and engineering lifespan.
