GRC Service Life: Influencing Factors and How to Extend It

The durability of architectural decoration materials directly affects the quality and lifespan of a project. As a new material combining both strength and aesthetics, GRC's service life has always been a core concern for designers and developers. Qinglong Group, a national high-tech enterprise with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, draws on over a thousand engineering projects to provide an in-depth analysis of the factors affecting GRC service life and scientific methods for extending it.

The Foundation of GRC Longevity: Comprehensive Control from Raw Materials to Production Processes

GRC (glass fiber reinforced concrete) has a theoretical service life of more than 50 years, but in practical applications it is constrained by multiple factors. In production, Qinglong Group strictly implements the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), using high-purity alkali-resistant glass fibers combined with low-alkalinity cement to ensure crack resistance and weather resistance at the source. Compared with ordinary cement products, Qinglong GRC achieves a flexural strength of over 20 MPa and withstands more than 300 freeze-thaw cycles, laying a solid foundation for long-term use.

Three Key Influencing Factors: The Combined Effect of Environment, Workmanship, and Maintenance

The natural environment is the primary challenge to GRC's lifespan. In areas with high humidity, strong ultraviolet radiation, or industrial pollution, the material is prone to surface weathering and fiber aging. By adding specialized anti-permeability agents and UV stabilizers, Qinglong has increased the service life of GRC in coastal high-salt-mist areas by 40%. Secondly, installation workmanship directly affects structural safety. Qinglong's proprietary BIM + 3D scanning installation technology achieves component tolerances of ≤2mm, preventing cracking risks caused by stress concentration. In addition, a lack of systematic maintenance accelerates aging—for example, in one commercial complex project, failure to promptly clean surface stains tripled the local carbonation rate.

Four Practical Strategies for Extending GRC Service Life

Scientific material selection is key. Qinglong provides customized solutions for different scenarios: municipal projects use high-flexural-strength GRC components, while underground works receive enhanced anti-corrosion treatment. Secondly, refined installation cannot be overlooked. Qinglong's team, holding Grade II professional contracting qualification for architectural decoration, strictly implements the "reserved expansion joints + elastic sealing" technique to effectively release thermal stress. For regular maintenance, annual surface cleaning and sealant renewal are recommended; Qinglong's after-sales team provides full life-cycle maintenance services including non-destructive testing. Finally, avoid overloading—for instance, GRC curtain wall design requires rigorous wind load calculations. The General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC), which Qinglong participated in developing, provides a safety standard for the industry.

As a member of the International GRC Association, Qinglong Group takes "creating beautiful architecture" as its mission and regards material durability as its brand's lifeline. From the GRC curtain wall at the Dongguan Women and Children's Activity Center (winner of the AALBORG WHITE Innovation Award) to the translucent concrete project at Century Plaza on Nanjing East Road, Qinglong's 28 years of professional experience prove that through scientific material selection, refined construction, and systematic maintenance, GRC can fully achieve the design goal of lasting as long as the building itself. Choosing a manufacturer with full-chain service capability is a wise decision to ensure GRC delivers stable, long-term performance.
