How to Improve the Wear Resistance of GRC Panels? Wear-Resistant Technologies and Qinglong Group's Surface Strengthening Solutions

Improving the abrasion resistance of GRC panels requires the comprehensive measures of "aggregate optimization, fiber reinforcement, and surface treatment." High-quality products should have an abrasion value ≤0.5g/cm² (ball method), one-third that of ordinary concrete. In flooring projects such as the Nanning Liyuan Hotel and Shenzhen Pingshan High-Tech Zone, Qinglong Group adopted emery aggregate (Mohs hardness ≥7), added steel fiber (2% by volume), and applied surface hardener treatment (hardness ≥HRC50), increasing GRC abrasion resistance by 300% and achieving a service life of over 20 years. Abrasion resistance not only affects the retention of appearance but also directly relates to safety in use, which is especially critical in densely populated areas.

Abrasion-Resistant Aggregate and Mix Proportion Design

Aggregate hardness is the foundation of abrasion resistance. We select premium abrasion-resistant aggregates such as garnet and corundum, with particle size grading of 0.3-1.2mm and volume fraction ≥60%. Through maximum-density packing, porosity is reduced below 8% and the abrasion value is kept at 0.3-0.4g/cm².

Fiber Reinforcement and Interface Strengthening

Steel fibers (12-20mm in length) bridge micro-cracks, raising impact resistance to 15kJ/m². Qinglong Group uses hooked-end fibers, increasing anchorage force by 30%. A penetrating hardener brushed onto the surface achieves Mohs hardness 6, extending abrasion-resistant service life fivefold.

Qinglong Abrasion-Resistant Panel Project Cases

In the Hainan Airport pedestrian street project, the abrasion-resistant GRC panels showed no obvious wear after 5 years of use. We provide abrasion test reports as a basis for design and product selection. Scientific abrasion-resistant design keeps high-traffic areas looking new for the long term.
