GRC (Glassfiber Reinforced Concrete) material is an advanced engineered composite that combines the strength of concrete with the flexibility of fibers. It is widely used in external facades, decorations, and architectural elements due to its light weight and high rigidity. [1, 2, 3, 4] Key Components Cement: White or ordinary Portland cement is preferred in high proportions. Silica Sand: The silica purity must be high, and its diameter should not exceed 1 mm. Glass Fibers (Fiberglass): It is required to contain a percentage of "zirconium oxide" of no less than 16% to resist alkalis and rust. Water and Additives: Additives to reduce water permeability and improve
