How to Maintain GRC? A Comprehensive Analysis of Daily Operations and Optimization Strategies for GRC Systems

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its lightweight, high-strength, and design-flexible characteristics. However, after GRC is put into use, many project managers often neglect scientific maintenance, leading to performance degradation and shortened service life. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group fully understands the importance of scientific maintenance in extending the service life of GRC components and ensuring building safety. This article systematically analyzes the key points of daily operation and optimization strategies for GRC systems, providing professional guidance for designers and owners.

The Core Value of GRC Maintenance: Why It Is Necessary from the Perspective of Material Properties

GRC material is a composite of cement, glass fiber, aggregates, and other components, combining the durability of concrete with the toughness of glass fiber. However, its surface pore structure and fiber-matrix interface characteristics make it susceptible to environmental factors during long-term use. For example, efflorescence may occur in humid environments, ultraviolet radiation can cause surface fading, and extreme temperature differences may trigger micro-cracks. The Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong Group participated in drafting, clearly states that standardized maintenance can extend the service life of GRC components to more than 50 years, far exceeding the 20-30 years without maintenance.

Daily Operation and Maintenance: Building a Full-Cycle Management System

Daily maintenance should follow the principle of "prevention first, combining prevention with treatment," focusing on the following key aspects:

1. Regular Inspection and Cleaning: It is recommended to conduct visual inspections quarterly, focusing on issues such as loose anchor points, surface cracks, and sealant aging. Use neutral detergents for cleaning and avoid acidic or alkaline solutions to prevent surface corrosion. In the Century Plaza renovation project on Nanjing East Road, Qinglong's maintenance team used a customized cleaning plan that kept translucent GRC components free of noticeable discoloration for 8 years.

2. Structural Safety Monitoring: Test the load-bearing performance of GRC components annually, including flexural strength (which should remain above 20MPa) and anchoring system tension. Drone inspection combined with 3D scanning technology can be used to accurately capture deformation data. Qinglong's self-developed RFID chip traceability system can record the stress state and environmental parameters of components in real time.

3. Environmental Adaptability Treatment: Take differentiated measures for different climate zones. In cold regions, check the drainage system before winter to prevent freeze-thaw damage; in coastal areas, strengthen anti-salt-spray treatment by applying Qinglong's special protective coating to enhance corrosion resistance.

Optimization and Upgrade Strategies: From Passive Maintenance to Proactive Management

With the development of building technology, GRC maintenance has shifted from simple repair to performance optimization:

1. Material Performance Improvement: Through technologies such as incorporating nano silica fume and modified fibers, Qinglong's new-generation GRC products have achieved a 40% improvement in impermeability and a 30% increase in crack resistance, reducing maintenance needs at the source. The General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC), which it participated in drafting, also provides a standard basis for the combined application of GRC and UHPC.

2. Intelligent Monitoring Systems: Smart GRC components integrated with temperature and humidity sensors and strain gauges can transmit data in real time to management platforms, enabling early warning of abnormal conditions. Qinglong applied this technology in the Dongguan Women and Children's Activity Center project, shortening maintenance response time to within 2 hours.

3. Green Maintenance Solutions: Use materials such as water-based eco-friendly coatings and biodegradable sealants to reduce chemical pollution. Qinglong's self-developed biodegradable cleaning agent achieved zero-emission maintenance in a commercial complex project in Zhongshan.
