Research on the Fire Performance of GRC — Qinglong GRC Fire Safety Advantages

GRC's fire performance meets the Class A non-combustible material standard, with a fire resistance limit of ≥2 hours and no release of toxic gases at high temperatures. Qinglong GRC products have been tested by the National Center for Quality Supervision and Testing of Fire Building Materials, achieving GB8624 Class A combustion performance. Their fire integrity and thermal insulation both meet code requirements, making them an ideal fire-resistant building material.

Fire test data: At 800°C high temperature, GRC specimens remain intact without cracking; in a 120-minute fire resistance test, the temperature rise on the unexposed side is ≤140°C; combustion heat value ≤2MJ/kg; smoke density grade ≤15. A commercial complex using Qinglong GRC fireproof panels passed fire acceptance inspection, buying precious time for personnel evacuation.

Non-Combustibility Advantages

The main components, cement and sand, are non-combustible materials; melting point ≥1000°C, no burning at high temperatures; no flammable components, safe and reliable; passed Class A fire testing. Non-combustibility guarantees basic safety.

Fire Resistance Performance

Standard fire walls have a fire resistance limit of ≥2 hours; good integrity with no penetrating cracks; excellent insulation with slow temperature rise on the unexposed side; superior fire performance of load-bearing components. Fire resistance ensures safety at critical moments.

Stable High-Temperature Performance

No strength loss below 400°C; residual strength ≥70% at 600°C; remains intact at 800°C; good thermal shock stability with no cracking under rapid cooling. High-temperature performance is stable and reliable.

Safety and Environmental Features

No toxic gas release during combustion; low smoke density that does not impede evacuation; no dripping when exposed to fire and no flame spread; can continue to be used after a fire. Dual assurance of environmental protection and safety.

GRC's outstanding fire performance safeguards building safety. Qinglong GRC products have passed rigorous testing, making them a safe choice.
