Does GRC Meet Fire Performance Standards? An In-Depth Analysis of GRC Material Fire Performance and Industry Standard Requirements

In the field of architectural decoration materials, fire resistance is one of the key indicators for measuring material safety. As a new material widely used in various types of buildings, whether GRC (Glass Fiber Reinforced Concrete) meets fire performance standards has always been a focus of attention for designers, owners, and developers. This article provides an in-depth analysis of the fire performance of GRC materials from the perspectives of industry standards, material characteristics, and practical application cases, and, drawing on Qinglong Group's 28 years of industry experience, offers professional reference for readers.

The fire performance of GRC materials must first meet the explicit requirements of national and industry standards. According to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), the combustion performance of GRC products should reach no lower than Class A2 (flame-retardant materials) or Class A (non-combustible materials) as specified in GB8624. This standard imposes strict specifications on the raw material ratios, production processes, and finished product testing of GRC, ensuring that it can effectively slow the spread of fire and reduce the release of harmful gases in the event of a fire. As a participating unit in the formulation of this standard, Qinglong Group has always regarded fire performance as a core indicator of product R&D. By optimizing the ratio of glass fiber to cement-based materials, the fire resistance rating of its GRC products has stably reached Class A, providing a solid guarantee for building safety.

From the perspective of material characteristics, GRC's fire resistance advantages stem from its unique composition. As a reinforcing material, glass fiber offers good thermal stability at high temperatures, while cement-based materials are inherently inorganic and non-combustible. GRC products formed by combining the two not only feature high strength and good toughness, but also possess excellent high-temperature resistance. In practical tests, Qinglong GRC products maintained their structural integrity in an 800°C high-temperature environment without any dripping. This characteristic makes them particularly suitable for crowded public buildings such as grand theaters, convention and exhibition centers, and commercial complexes. Compared with traditional decorative materials, GRC's advantages in fire safety are especially prominent. For example, its fire performance is superior to that of some organic composite materials, and its weight is only 1/4 that of stone, which can reduce building loads while enhancing fire safety factors.

In engineering applications, the fire performance of GRC has been verified by numerous projects. In the Dongguan Women and Children's Activity Center project undertaken by Qinglong Group, the large-area application of GRC exterior wall cladding panels not only achieved complex architectural forms, but the panels' fire performance also passed rigorous on-site testing, laying the foundation for the project to win the "Silver Award of the First GRC Construction Engineering Innovation Award (AALBORG WHITE Cup)". In addition, in the renovation project of Century Plaza on Nanjing East Road, the combined application of Qinglong translucent concrete (UHPC) and GRC met the building's aesthetic requirements while enhancing the project's safety level through dual fire protection. These cases fully demonstrate that GRC materials can fully meet the stringent fire performance requirements of high-end buildings, making them an ideal choice for designers to achieve a balance between safety and aesthetics.

For professional clients such as real estate developers and architectural designers, choosing GRC materials that meet fire standards is not only a basic requirement for regulatory compliance, but also a reflection of responsibility for project safety and quality. As a national high-tech enterprise and a "Specialized, Refined, Distinctive, and Innovative" enterprise, Qinglong Group has a complete quality control system and full-chain service capabilities. From detailed design to production and installation, it strictly follows fire protection standards to ensure that every GRC product complies with safety regulations. Meanwhile, the professional technical support provided by the company can help clients optimize fire protection design solutions based on project characteristics, achieving a precise match between material performance and engineering requirements.
