The anti-aging performance (durability) of GRC products is crucial, directly determining their service life and maintenance costs. Factors affecting GRC durability include the alkali resistance of fibers, the impermeability of the cement matrix, freeze-thaw resistance, and carbonation resistance. Under the long-term effects of environmental factors such as ultraviolet rays, moisture, temperature changes, and harmful ions, GRC with degraded performance may suffer from problems such as reduced strength, surface powdering, and fiber corrosion (if steel fibers are used).

Qinglong, as a GRC manufacturer, attaches great importance to the long-term durability of its products and has adopted a series of effective measures. Foremost is ensuring the long-term alkali resistance of the glass fibers: Qinglong selects zirconia-type alkali-resistant glass fibers (with high zirconium oxide content) and reduces the alkalinity of cement hydration products through mix proportion design, slowing the erosion of the fibers. By preparing a cement matrix with a low water-cement ratio and high density, the intrusion of moisture and harmful ions is effectively blocked, which is the foundation for improving freeze-thaw resistance and impermeability. Depending on the climate and environmental characteristics of the project location, special anti-aging additives (such as polymer latex powder and hydrophobic agents) may be added to the formulation to further enhance durability. A strict curing regime ensures full hydration and reduces internal defects. In addition, surface treatment of finished components (such as spraying a weather-resistant protective agent) serves as another effective line of defense. Qinglong GRC products have been verified through accelerated aging tests and have withstood long-term trials in actual projects (such as projects in coastal and high-humidity regions), demonstrating excellent anti-aging performance with a design service life of over 50 years. In contrast, some manufacturers may focus more on short-term strength while neglecting long-term durability, or their products' anti-aging capability may be insufficient due to lax control of raw materials and production processes.

Long-Term Fiber Stability

Ensuring that glass fibers maintain their strength over the long term in the alkaline cement environment is the core of durability.

Matrix Impermeability

A dense matrix can effectively prevent environmental corrosive media from penetrating into the material interior.

Resistance to Special Environments

The ability to withstand special environments such as freeze-thaw cycles, salt corrosion, and acid rain.

Long-Term Performance Data

Whether there are accelerated aging test data and long-term project tracking data to provide support.

Therefore, when selecting a GRC manufacturer, focus should be placed on examining its technical measures for durability, relevant test reports, and examples of projects completed years ago (especially in areas with harsh environmental conditions). Qinglong GRC has deep expertise and successful engineering practice in durability technology.
