Which Building Parts Can GRC Be Used In? Common Application Scenarios and Design Points Explained

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight, high-strength, and flexible shaping characteristics, has become a key material for achieving the unity of architectural aesthetics and function. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has systematically outlined the innovative applications and design key points of GRC in various parts of buildings based on extensive engineering practice, providing professional reference for designers and owners.

I. Core Applications of GRC in Exterior Envelope Structures

GRC exterior wall cladding panels are its most classic application, especially suitable for high-end public buildings such as grand theaters and museums. Taking a cultural landmark project in Nanjing as an example, 30mm thick GRC cladding panels were used to achieve double-curved surface shapes, with a self-weight of only 1/4 of traditional stone, greatly reducing the load on the main structure. During design, attention should be paid to selecting the appropriate anchoring system according to the building height. For buildings over 100 meters, back-bolt connection is recommended, and BIM technology should be used to simulate panel layout to ensure joint errors are controlled within 2mm. The bending strength of GRC panels produced by Qinglong reaches 22MPa, meeting the highest grade requirements of the "Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018).

II. Innovative Practices of GRC in Decorative Components and Landscape Engineering

In commercial complexes and European-style buildings, GRC decorative moldings demonstrate outstanding expressiveness. Components such as Roman columns and cornice moldings can be precisely formed through molds, with surface texture richness comparable to stone carvings. A high-end villa area project used GRC sandstone-imitation moldings, and accelerated aging tests showed its weather resistance can reach more than 50 years. In the field of garden landscapes, components such as GRC benches and flower beds combine functionality with artistry. In the Dongguan Women and Children Activity Center project, the Qinglong team achieved a perfect fusion of translucent GRC and green plant walls through parametric design, winning the Silver Award of the First GRC Building Engineering Innovation Award.

III. GRC Applications and Technical Breakthroughs in Special Scenarios

Subway and utility tunnel projects impose strict requirements on material durability. GRC lining panels are widely adopted for their excellent impermeability and ease of maintenance. The GRC lining panels customized by Qinglong for a subway project incorporated nano-scale waterproofing agents, reducing the permeability coefficient to 1.0×10⁻¹²m/s. In the field of special-shaped structures, GRC demonstrates even greater advantages. For example, the curved shading system of an airport terminal used 3D scanning technology to ensure each GRC unit perfectly fits the steel structure, with installation accuracy controlled within ±3mm, demonstrating Qinglong's technical strength in realizing complex shapes.

IV. Key Points of GRC Design and Collaborative Innovation

Successful application of GRC requires mastering three cores: material mix optimization (glass fiber content should be controlled at 4-5%), precise structural calculation (using ANSYS for stress simulation), and coordination with other materials (such as combining with UHPC to enhance strength). As a drafting unit of the industry standard "General Technical Requirements for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," Qinglong recommends that designers involve GRC manufacturers in design development from the scheme stage, improving project efficiency through integrated "design-production-installation" services. Currently, Qinglong's GRC products have been exported to more than 10 countries including Australia and Saudi Arabia, setting an industry benchmark in landmark projects both at home and abroad.

With the advancement of building industrialization, GRC is upgrading from a decorative material to a structural-functional integrated material. Choosing a supplier with full-chain service capabilities, such as Qinglong Group, a national high-tech enterprise with a provincial-level R&D center and 58 patented technologies, is key to ensuring effective GRC application. In the future, the composite application of GRC with UHPC, GRG and other materials will provide more possibilities for architectural envelope innovation.
