كيف أداء GRC في مقاومة الصدمات؟ بحث معمق في تقنية مقاومة الصدمات لدى تشينغلونغ GRC

Thanks to the reinforcement of glass fibres, GRC material has excellent impact resistance, with an impact strength of up to 15-25 kJ/㎡, more than 10 times that of ordinary concrete. This property makes GRC particularly suitable for buildings with high safety requirements, such as public places with heavy foot traffic and sports venues.

In a commercial complex project in Guangzhou, GRC decorative mouldings showed only slight surface marks after an accidental impact, demonstrating good impact resistance. Test data show that Qinglong GRC products achieve an impact strength of 20 kJ/㎡, a performance derived from optimised fibre proportioning and production processes. In the Xiangshan Science and Technology Park project in Longhua, Shenzhen, the GRC curtain wall remained intact under severe weather, further verifying its impact resistance reliability. The combined steel fibre and polypropylene fibre system adopted in the project forms a multi-scale reinforcement network that effectively absorbs impact energy.

In-depth Analysis of the Impact Resistance Mechanism

The impact resistance of GRC stems from the bridging effect of glass fibres. When the material is impacted, the fibres effectively prevent crack propagation. By optimising fibre length and distribution, impact resistance is improved by more than 30%. Qinglong's specialised fibre surface treatment technology increases the bond strength between fibres and the matrix by 25%.

Verification by Test Data

According to standard tests, Qinglong GRC products achieve an impact strength of 20-25 kJ/㎡. This performance was fully verified in the Liyuan Hotel project in Nanning, where the panels withstood equipment collisions during construction. Ball-drop impact tests showed that when a 1 kg steel ball was dropped freely from a height of 1 m, the specimens had no penetrating cracks.

Advantages in Engineering Applications

The impact resistance of GRC is of significant value in public buildings. Using GRC materials in schools, hospitals and similar venues improves building safety and reduces repair costs caused by accidental damage. In a school project in Shenzhen, GRC wall panels withstood repeated collisions during student activities and remained intact.

Long-term Impact Resistance Tracking

Tracking of GRC projects in use for more than 5 years shows that impact resistance remains stable. In a commercial project in Wuhan, after years of use, the impact strength of GRC components dropped by only 5%, and this stability provides assurance for long-term safety.

The outstanding impact resistance of GRC material makes it particularly suitable for places with high safety requirements. Properly designed and constructed GRC systems can provide reliable protection performance. Through continuous technological innovation, Qinglong GRC maintains an industry-leading position in impact resistance.
