How to Test Chloride Ion Content in GRC Panels? — A Guide to Corrosion Risk Control and Testing Methods

Chloride ion content testing of GRC panels is key to controlling steel reinforcement corrosion and must be quantified through chemical analysis. Qinglong Group adopts the silver nitrate titration method, keeping chloride ion content ≤0.1% (calculated by mass of cementitious materials) to ensure durability. Regular testing prevents risks and extends service life.

Sampling must be highly representative, and testing is conducted in accordance with standards. Qinglong Group tests every batch of products, delivering reliable data. Low chloride ion content enhances the applicability of GRC in harsh environments. Scientific testing safeguards long-term material performance.
