What is GFRC Made With? - GC Products, Inc.

GFRC stands for “Glassfiber reinforced concrete,” and consists of concrete augmented with glass fibers. But in addition to the standard concrete elements and the glass, GFRC requires a range of ingredients. These contribute to the superior tensile strength, or ability to endure an impact, and durability of GFRC over standard concrete.

GFRC shares many of the same basic ingredients as concrete, although we use them at different ratios. These ratios and the addition of materials specific to GFRC are what make this product better able to withstand impacts and endure weather and time. The production time is also faster and the final product can be thinner and less than half the weight of concrete.

Materials We Use in GFRC

The ratio of materials in the GFRC mix, often known as the mix design, can be customized to best suit the way and place in which it will be used. The materials included in the mix design are:

• Portland Cement – The foundation of all concrete products, this acts as a binder to hold the other ingredients together in the GFRC.
• Sand – Sand works as an aggregate which forms the majority of concrete products. The size of the granules used determine the durability, texture, and weight of finished GFRC pieces, among other things.
• Water – Water works with the portland cement to create a paste that keeps the entire mixture bound. GFRC uses a lower ratio of water to other materials than standard concrete.
• Glass Fibers – We use glass fibers that are alkali resistant, meaning they won’t degrade over time due to the alkaline content of portland cement. These fibers are what give the GFRC its tensile strength and lighter weight.
• Polymer – Containing acrylic solids mixed with liquid, this additive enables the GFRC to cure in a day instead of the weeklong curing process of traditional concrete. The polymer also helps maintain GFRC strength over time and minimizes water absorption after installation.
• Chemical Additives – Other additives, like plasticizers, help make the GFRC easy to work with and mould despite the lower water content. These can be adjusted based on the purpose of the GFRC.

At GC Products, we use 100% recycled products. This further improves the sustainability of GFRC beyond the already low water usage in manufacturing and the longevity of the GFRC.

With decades of experience in GFRC manufacturing, we have perfected our mixing process. All of our custom made GFRC uses a mixture of ingredients that will create the right look and maintain its durability for years to come.

What is GFRC?

Definition and Core Components

Glass Fiber Reinforced Concrete, commonly known as GFRC, is a specialized form of concrete that uses glass fibers to enhance its structural properties. Unlike traditional concrete, GFRC comprises a cementitious skin reinforced with alkali-resistant glass fibers, resulting in a highly durable and flexible material. This composite panel is typically 3/4″ thick and attached to a metal stud frame system.

Manufacturing Process

The manufacturing of GFRC panels involves a meticulous process to ensure precision and quality. The process begins with the custom face mix sprayed into a mold, followed by multiple passes of glass fiber reinforced concrete to achieve the desired thickness. The structural frame, usually made of structural tube members, is integrated with the GFRC using L or T-shaped galvanized pins. Once cured, the panels are stripped from the mold and sandblasted to the architect’s specifications.

Specializations at Willis Construction

At Willis Construction, we specialize in creating GFRC panels that cater to diverse architectural needs. Our expertise includes producing panels with intricate shapes, multiple colors, and finishes, including light and heavy sandblast textures. We also offer custom form liners to emulate materials such as wood, limestone, and brick, providing limitless design possibilities.

Benefits of GFRC Solutions

Durability and Longevity

GFRC is renowned for its exceptional durability and longevity. Its composition makes it resistant to environmental factors, reducing the need for frequent maintenance and repairs. This resilience ensures that structures built with GFRC maintain their aesthetic and functional integrity for years to come.

Aesthetic Versatility

One of GFRC’s standout features is its aesthetic versatility. Architects can choose from a wide range of colors, textures, and finishes to match their design vision. The ability to create intricate shapes and emulate other materials adds to its appeal, making GFRC a preferred choice for innovative architectural projects.

Cost-Effectiveness

GFRC offers significant cost savings through reduced material and labor costs. Its lightweight nature means less structural support is needed, leading to savings in steel and foundation costs. Additionally, the prefabricated panels speed up the installation process, minimizing on-site labor and reducing project timelines.

Environmental Sustainability

Incorporating GFRC into construction projects supports sustainable building practices. The material’s high strength-to-weight ratio reduces the overall carbon footprint, and its durability extends the lifespan of structures, decreasing the need for resource-intensive repairs and replacements.
