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

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 uses zirconia-type alkali-resistant glass fibers (with high zirconium dioxide content) and lowers the alkalinity of cement hydration products through mix design, slowing the erosion of the fibers. By producing a cement matrix with a low water-cement ratio and high density, the ingress of moisture and harmful ions is effectively blocked, which forms the basis for improved 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 mix to further enhance durability. Strict curing regimes ensure full hydration and reduce internal defects. In addition, surface treatment of finished components (such as spraying weather-resistant protective agents) provides another effective line of defense. Qinglong GRC products have been verified through accelerated aging tests and have withstood long-term tests in actual projects (such as projects in coastal and high-humidity regions), demonstrating excellent aging resistance with a design service life of over 50 years. By comparison, some manufacturers may focus more on short-term strength while neglecting long-term durability, or their products may have insufficient aging resistance 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.

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 as support.

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