GFRC (Glass Fiber Reinforced Concrete)

Glass Fiber Reinforced Concrete (GFRC) is a composite material that combines the strength and durability of concrete with the tensile strength and flexibility of glass fibers. The glass fibers are embedded within the concrete matrix, creating a material that is lighter, more resistant to cracking, and more easily formed into complex shapes than traditional concrete. 

GFRC is a relatively recent development in the construction industry, dating back to the mid-20th century. Its use has become more widespread in recent years due to its versatility and benefits over traditional concrete. 

GFRC can be used to create intricate and visually appealing façades for buildings. Its lightweight nature makes it easier to install and can reduce the overall weight of the structure. Additionally, GFRC can be used to create a variety of architectural elements, such as columns, capitals, and decorative panels. Its ability to be precast into various shapes and sizes allows for faster construction and reduced on-site labor. 

EXAMPLES IN CHICAGO:  

1. Millennium Park: GFRC was used to create the iconic Cloud Gate sculpture, also known as "The Bean," which is a popular attraction in the park. 
2. McCormick Place Convention Center: GFRC was used for some of the exterior cladding and interior finishes in the convention center.
