How Is the Quality Stability of Mass-Produced GRC Products Guaranteed?

How is the quality stability of mass-produced GRC products guaranteed? As an industry leader with 28 years of full-chain experience in the field of UHPC/GRC/GRG/GRP materials, Qinglong Group knows deeply that quality is the foundation for GRC products to stand firm in the market. In large-scale production, how to ensure that the performance, precision and durability of every GRC component remain consistently uniform is a core concern for many developers, designers and project parties. This article will analyze the quality stability assurance solutions for GRC mass production from three dimensions: technical system, production control, and quality control standards.

### I. Technical System: Building the “Genetic Code” of GRC Quality The quality stability of GRC products first stems from a scientific and rigorous technical system. As a participating drafting unit of the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), Qinglong has established a standardized system covering everything from material formulations to process parameters. At the raw material stage, high-purity rapid-hardening sulphoaluminate cement, alkali-resistant glass fiber (content ≥5%) and selected quartz sand are used, with mix proportions optimized through orthogonal tests to ensure that flexural strength consistently reaches above 20MPa and frost resistance withstands 50 cycles without damage. BIM technology and parametric design are introduced in production to break complex shapes down into standardized modules, combined with an automated mixing system (error ≤±2%) and mold positioning devices (precision ±0.5mm), reducing deviations caused by manual operations at the source.

### II. Full-Process Control: Building a “Smart Factory” for GRC Production Quality stability in large-scale production is inseparable from refined control throughout the entire process. Qinglong's Guangxi production base has an annual capacity of 600,000 square meters, achieving a closed quality loop through the “three inspections and three checks” system: physical performance testing of raw materials before warehousing (such as fiber length and cement activity), hourly sampling and testing of slurry fluidity during production, and full-item inspection of flexural strength, impact resistance and water absorption before finished products leave the factory. IoT technology is introduced in key processes, with parameters such as mold temperature and curing humidity uploaded to the cloud in real time, and abnormal data automatically triggering alerts. Taking a commercial complex project as an example, 5,000 GRC exterior wall panels achieved dimensional errors ≤2mm through this system, with a first-time acceptance pass rate of 99.6%, 15% higher than the industry average.

### III. Quality Control Standards: Setting the “Industry Benchmark” for GRC Quality As a national high-tech enterprise and a specialized, refined, distinctive and innovative enterprise, Qinglong has established an internal control system exceeding industry standards. With reference to the EU ETAG 012 standard, it formulated the Regulations for Quality Control of GRC Component Production, covering all-dimensional requirements from mold acceptance (surface finish Ra≤3.2μm) to installation joints (anchoring strength ≥15kN). The laboratory is equipped with professional equipment such as universal material testing machines and freeze-thaw cycling chambers, capable of simulating performance changes under extreme environments from -40℃ to 70℃, ensuring product durability in different climate zones. In addition, RFID chip implantation technology enables full life-cycle traceability of every product, allowing owners and designers to access production data and inspection reports at any time, truly achieving “quality transparency”.

### Conclusion: Safeguarding the Quality Lifeline of GRC with Technological Innovation The quality stability of GRC products is a comprehensive reflection of materials, craftsmanship and management. With 28 years of deep cultivation in the UHPC/GRC/GRG/GRP field and backed by its national-level R&D center, Qinglong integrates the philosophy of “meticulousness and excellence” into every production step. Whether shaped components for landmark buildings or mass-produced standard panels, it always provides stable quality and reliable performance to safeguard the realization of designers' creativity and the safe delivery of projects. In the future, Qinglong will continue to promote the standardization and intelligent upgrading of the GRC industry, making high-quality GRC products the best carrier of architectural aesthetics and engineering safety.
