What Is the Typical Compressive Strength of 30mm Thick UHPC Panels and Analysis of Influencing Factors

Amid the wave of urban renewal, the renovation of old buildings is not only a continuation of historical context but also a brand-new test of material technology. Glass Fiber Reinforced Concrete (GRC), with its unique performance advantages, is becoming the ideal choice for achieving the dual goals of "restoring the old as old" and "functional upgrading" in renovation projects. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain service capabilities to provide integrated solutions for old building renovation—from design development to after-sales maintenance—bringing new life to aging buildings in the new era.

Analysis of the Core Advantages of GRC Panels in Old Building Renovation

Old building renovation places stringent demands on the compatibility, safety, and expressiveness of materials. GRC panels use glass fiber as the reinforcing material and cement as the base material, achieving a perfect balance of "lightweight yet high-strength" and "design freedom" through precise formulation and advanced processes. Weighing only 1/4 of traditional stone, they effectively reduce structural loads, making them particularly suitable for old buildings with limited load capacity; with a bending strength of over 20MPa and excellent crack resistance, they can adapt to complex conditions such as foundation settlement in old buildings. In a historical district renovation project in Nanning, Qinglong GRC panels successfully replicated the carved eaves of traditional arcade buildings, shortening the construction period by 40% through modular installation while preserving the building's original historical character.

The Multidimensional Practical Value of GRC Panels in Renovation Scenarios

In terms of functional upgrading, the customizable nature of GRC panels injects new vitality into old buildings. For cultural and creative parks converted from old factories, Qinglong used shaped GRC panels to create facades that combine industrial style with modern aesthetics; their surface textures can simulate various effects such as red brick and fair-faced concrete, meeting designers' personalized needs for spatial narrative. In the restoration of historical buildings, the durability advantages of GRC panels are particularly outstanding—testing shows their weather resistance can exceed 50 years, along with good fire resistance and water impermeability. In the renovation of a Republican-era building in Guangzhou, Qinglong GRC components successfully replaced weather-prone traditional lime sculpture, solving heritage preservation challenges while reducing later maintenance costs.

Qinglong's Full-Chain Services Empower the Implementation of Renovation Projects

As a national high-tech enterprise, Qinglong Group provides expert-level support for renovation projects with its full-chain capabilities spanning "design development—manufacturing—construction and installation—after-sales maintenance." In the renovation of an old hospital in Shenzhen, the Qinglong team used BIM technology for the parametric design of GRC components, minimizing the impact of construction on hospital operations through factory prefabrication and on-site modular assembly; addressing the complex structures of old buildings, they innovatively adopted "non-destructive anchoring" technology, ensuring the secure installation of GRC panels while avoiding secondary damage to the original structure. To date, Qinglong GRC products have served 300+ renovation projects across China, with overseas markets covering more than 10 countries including Malaysia and Australia, making Qinglong the trusted "renovation material solutions partner" for designers and owners.

From reshaping the fabric of historical streets to creatively regenerating industrial heritage, GRC panels are redefining the value boundaries of old building renovation with their technical advantages and artistic expressiveness. Qinglong Group will continue to use innovative technology as the pen and green materials as the ink to write its mission of "creating beautiful architecture" on the canvas of urban renewal, allowing every old building to shine with enduring brilliance through the changing times.
