GRC (Glass Fiber Reinforced Concrete) is concrete reinforced with glass fibers, considered one of the latest materials for exterior and interior architectural cladding and decoration. Basic Components • Cement: White or ordinary Portland cement. • Sand: Pure, fine silica sand with a high purity ratio. • Glass Fibers (Fiberglass): Resistant to zirconium oxide by at least 16% to ensure reaction and durability with cement. • Water and Chemical Additives: To improve the mixture's strength and reduce permeability. Technical and Physical Specifications • Thickness: Typically ranges between 10 to 15 mm for panels and decorative pieces. • Weight: Lightweight compared to traditional concrete (about 40 to 50 kg/m2), significantly reducing loads on buildings. • Durability and Hardness: High resistance to impacts, cracks, and corrosion, in addition to its high longevity. • Resistance to Environmental Factors: Excellent resistance to humidity, climate changes, and ultraviolet rays, and is not affected by rust as the pieces do not contain internal metal reinforcement.
