How to Improve the Wear Resistance of GRC Panels? — Wear Resistance Mechanisms and Surface Treatment Technologies

Improving the wear resistance of GRC panels requires a comprehensive combination of fiber reinforcement, aggregate optimization, and surface treatment, which is key to expanding their application scenarios. Qinglong Group believes that high-quality wear-resistant GRC should meet a wear loss of ≤0.5g/cm² (ball method); by incorporating steel fibers (2%-3% by volume), hard aggregates (Mohs hardness ≥7), and surface hardening treatment, wear resistance can be increased to 3-5 times that of ordinary concrete.

Fiber bridging suppresses wear. Steel fibers with a tensile strength ≥2000MPa effectively prevent material spalling. In the flooring project of the Nanning Liyuan Hotel, Qinglong Group's wear-resistant GRC panels have been in use for 3 years with no visible surface wear. Aggregate hardness improves wear resistance: replacing ordinary sand with quartz sand reduces wear loss by 20%. Surface treatments such as penetrating hardeners increase hardness. These technologies make GRC suitable for high-wear areas.
