Application of Glass Fibre Reinforced Concrete (GFRC) in Precast Industry for Facade Applications

Abstract

The precast industry has seen significant growth in the usage of Glass Fibre Reinforced Concrete (GFRC) for facade applications. A lightweight, high-performance material ideal for architectural applications, GFRC is a composite made of a cementitious matrix reinforced with glass fibres resistant to alkalis. The main advantages and factors to be considered when using GFRC in the precast industry for facades are highlighted in this abstract. This property enables the fabrication of lighter, thinner panels without sacrificing structural integrity, which lowers the cost of transportation and installation. To achieve the desired strength, workability, and aesthetics, mixed design—which includes the choice of cementitious materials, aggregates, and glass fibres—must be carefully considered. High-quality GFRC panels must be produced using precise manufacturing processes, such as spray-up or premix casting. Although employing GFRC in precast facades has benefits, there are drawbacks as well. Surface finishing and sealing must receive attention to maintain the intended appearance and in conclusion, using GFRC for facade applications in the precast sector has many advantages in terms of strength, weight reduction, durability, and aesthetics. GFRC may offer architects and engineers flexible and cutting-edge materials for developing aesthetically pleasing and useful facades by carefully addressing mixture design, manufacturing methods, and installation processes. To use GFRC to its full potential in precast facade applications, handling, surface finishing, and financial obstacles must be removed. The application of GFRC in the precast sector will be significantly improved through research and technological breakthroughs, creating exciting new opportunities for architectural design and construction.
