The basic components of GRC Cement: Ordinary or white Portland cement is used to form the binding base. Glass Fibers (Fiberglass): Must be alkali-resistant (AR Glass) to give the material tensile and flexural strength. Silica Sand: Pure, clean sand with a high silica content and fine grading. Water: Pure water free from harmful salts and impurities. Chemical Additives: Additives to improve cohesion and reduce water permeability. [1, 2, 3, 4] Technical and Physical Specifications Thickness: Usually starts from 15 mm for light and decorative elements and increases according to structural requirements. Weight: Characterized by light weight compared to ordinary concrete and natural stone. Permeability: Low permeability to water and moisture, making it resistant to erosion. Fire Resistance: Possesses excellent specifications and high resistance to fire. Durability: High strength in تحمل and resistance to impact, cracks, and weather changes. [1, 2, 3] Advantages and Uses Flexibility: Easy to mold to create complex geometric and decorative shapes, cornices, and columns. Coloring: Can be dyed and painted with all types of paints. Installation: Attached to building facades using steel structures and galvanized screws.
