How to Improve GRC Panel Wear Resistance: Research on Key Technologies and Practical Approaches

In the field of architectural decoration, material durability directly affects a building's aesthetic lifespan and safety performance. GRC (Glass Fiber Reinforced Concrete), as a new material combining design freedom with structural stability, has long made the improvement of its wear resistance a focal point of industry attention. Qinglong Group, a national high-tech enterprise with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, draws on full-chain technical experience—from material formulation optimization and process innovation to application scenario adaptation—to deliver a systematic solution for enhancing the wear resistance of GRC panels, providing designers and owners with solutions that combine aesthetic and practical value.

Core Factors Influencing the Wear Resistance of GRC Panels and Industry Challenges

The wear resistance of GRC panels is jointly determined by three key factors: matrix material strength, the fiber reinforcement system, and the surface treatment process. Traditional GRC products often suffer from surface sanding and insufficient wear resistance due to unreasonable cement matrix mix ratios, uneven glass fiber dispersion, or inadequate curing processes—especially in high-traffic settings such as commercial complexes and metro stations, where scratches and damage easily occur. According to industry research, non-optimized GRC panels typically see their service life shortened by more than 30% under moderate-load friction. Through its participation in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong has gained deep insight into how material performance matches application environments, laying a theoretical foundation for improving wear resistance.

Material Formulation Optimization: From Matrix Strengthening to Fiber Synergy

The key to improving the wear resistance of GRC panels lies in building a high-strength, highly dense cement matrix. Qinglong optimizes the mix ratio using “dual-blending technology”: on one hand, introducing ultra-fine silica fume and mineral powder composite admixtures to refine cement hydration products and reduce porosity; on the other hand, adjusting the water-cement ratio to 0.28-0.32 in combination with high-efficiency water reducers, raising the matrix compressive strength to over 60MPa with surface hardness reaching Mohs 7. For fiber reinforcement, alkali-resistant glass fibers with a zirconia content of ≥16% are selected and applied using a three-dimensional randomly distributed process, ensuring a 20% increase in fiber-matrix interfacial bond strength and effectively suppressing microcrack propagation. Third-party testing shows that the optimized GRC panels achieve 40% higher wear resistance than traditional products, meeting the premium wear-resistance standard in the General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC) (Plan No. 2024-0232T-JC).

Process Innovation: Full-Process Quality Control from Production to Installation

At its production base in Nanning, Guangxi, Qinglong has introduced an automated material distribution system and a steam curing process, precisely controlling forming pressure (0.8-1.2MPa) and curing temperature (60-80℃) to ensure the uniformity of the internal structure of GRC panels. For surface wear-resistant treatment, Qinglong developed a “penetrating silane-modified coating” technology: nano-scale silane molecules penetrate and fill surface pores, forming a dense protective layer 5-8μm thick that not only enhances wear resistance but also strengthens waterproofing and stain resistance. During construction and installation, BIM-based pre-assembly and 3D laser positioning ensure flat joints and prevent localized stress concentration wear caused by installation errors. This full-chain process system enabled Qinglong GRC panels to withstand daily foot traffic of 100,000 people in projects such as the Century Plaza renovation on Nanjing East Road, maintaining a surface integrity rate above 95%.

Scenario-Based Solutions: Wear-Resistance Strategies Matching Different Application Needs

To meet wear-resistance needs across different application scenarios, Qinglong provides customized solutions: for commercial complex exterior walls, a “GRC+UHPC composite panel” structure leverages the ultra-high wear resistance of a UHPC surface layer (5-10mm thick, wear amount ≤0.1g/cm²) to resist wind and sand erosion; for garden landscape benches and other areas subject to frequent contact friction, aluminum oxide wear-resistant aggregate is added with a bush-hammered surface finish, raising the friction coefficient to 0.8; for metro tunnel decoration, anti-static wear-resistant GRC panels were developed, achieving a surface resistance of ≤10⁸Ω through carbon fiber doping to meet both wear-resistance and safety requirements. These solutions have been successfully applied in real estate projects by Poly, China Overseas, and others, as well as overseas projects in Malaysia and Saudi Arabia, verifying their adaptability and reliability.

As a participant and leader in GRC industry standard-setting, Qinglong has always upheld the mission of “creating beautiful architecture.” Through material technology innovation and full-process quality control, it continuously pushes the performance boundaries of GRC panels. Looking ahead, with the deepened application of UHPC and GRC composite technology, Qinglong will continue to provide designers with more expressive and durable decorative material solutions, driving the architectural decoration industry toward high quality and long service life. Choosing Qinglong GRC is not just choosing a material—it is choosing a system solution proven by 28 years of engineering practice.
