What Quality Risks Might Low-Priced UHPC Products Have?

In the field of architectural decoration materials, UHPC (Ultra-High Performance Concrete), with its outstanding mechanical properties and design freedom, is becoming the new favorite of high-end construction projects. However, the low-price UHPC products emerging on the market conceal quality risks. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has a responsibility to reveal the risks behind low prices to designers and owners, helping them make project decisions.

I. Core Quality Risks of Low-Price UHPC Products

1. Cutting Corners on Raw Materials, Greatly Compromised Performance

High-quality UHPC requires core raw materials such as cement of specific strength grades, ultra-fine silica fume, and steel fibers. Some low-price products, in order to cut costs, may use ordinary cement instead of special cement, or reduce the steel fiber content (the steel fiber volume content of high-quality UHPC is usually ≥2%). This directly results in compressive strength below 150MPa and flexural strength below 20MPa, seriously affecting structural safety. Qinglong's production base strictly implements an incoming raw material inspection system to ensure that every batch of materials complies with the industry standard “General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components”.

2. Simplified Production Processes, Questionable Durability

UHPC places extremely high demands on mixing, forming, and curing processes. Low-temperature curing or omitting the steam curing step leads to insufficient hydration reactions and micro-cracks on the surface. One low-price project case showed that UHPC components that had not undergone standard curing began to chalk within 1 year under ultraviolet exposure. Qinglong has modern production lines with an annual capacity of 600,000 square meters, adopting fully automatic mixing systems and constant temperature and humidity curing kilns to ensure a 100% compliance rate for 28-day strength.

3. Lack of Detailed Design, Prominent Installation Risks

Low-price suppliers often lack professional detailed design capabilities and give insufficient consideration to joint construction and load calculations. For example, in a commercial complex project, low-price UHPC cladding panels without wind load verification showed panel displacement after installation. As a National High-Tech Enterprise, Qinglong is equipped with a BIM technical team and can provide full-process services from parametric design to installation guidance. Its Nanjing East Road Century Plaza renovation project won the Silver Award of the UHPC Construction Engineering Innovation Award.

II. How to Avoid the Low-Price UHPC Trap?

1. Verify Company Qualifications and Track Record

Give priority to companies like Qinglong that hold Grade II professional contracting qualifications for building curtain wall engineering and have participated in formulating industry standards (such as “Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)” JGJ/T423-2018), and review the completed results and service life of similar project cases (such as landmark buildings and high-end commercial complexes).

2. Request Complete Test Reports

Key indicators should include compressive strength, flexural strength, elastic modulus, carbonation depth, etc., and the testing institution should hold CMA certification. Qinglong's laboratory is a provincial engineering technology center and can provide authoritative testing data support.

3. Evaluate Full-Chain Service Capabilities

Integrated services from detailed design to after-sales maintenance are the key to quality assurance. Qinglong has offices across the country and can respond quickly to project needs. Its service motto of “meticulousness and constant pursuit of excellence” has been recognized by well-known real estate groups such as Poly and China Overseas.

III. Conclusion: Choose Value over Price

The value of UHPC materials lies not only in their physical properties, but also in their long-term guarantee of architectural aesthetics and safety. Low-price products may seem to reduce initial costs, but may actually incur higher full life-cycle costs due to repairs and replacements. As a leading UHPC/GRC/GRG/GRP manufacturer, Qinglong always adheres to the values of “honesty, hard work, trust, and collaboration”, providing customers with professional solutions from concept to completion, so that every project can stand the test of time.
