Material used in wall systems that resembles but generally does not perform as well as concrete. Usually a thin cementitious material laminated to plywood or other lightweight backing.
glass fiber reinforced concrete. A type of precast concrete used for architectural cladding and ornament. While glass fibers impart tensile strength to concrete, they are prone to damage due to alkali-silica reaction (ASR). MetaMax® is added to GFRC to mitigate ASR.
Glass Fiber Reinforced Concrete Concrete panels, usually architectural designs, reinforced with a high zirconia (16% minimum), alkali-resistant glass fiber. Optimum glass fiber content of 5% by weight. Lower fiber content results in lower early ultimate strengths, higher fiber content can produce composite compaction and consolidation difficulties.
