What is GFRC?
GFRC stands for Glass Fibre Reinforced Concrete. It represents a major advancement in the construction industry. A blend of fine sand, cement, water, chemical admixtures, and glass fibres, GFRC stands out for its remarkable strength, durability, and versatility. Think of it like a special kind of concrete that’s been made even stronger with tiny glass fibres. These fibres are mixed into the concrete and act like a super-strong net that holds everything together. This makes the concrete much stronger than regular concrete.
This innovative material allows for greater design flexibility, making it ideal for various architectural and decorative applications. It was made a long time ago, around the 1940s, but it has become popular only recently. People are using GFRC because it’s not just strong; it’s also lighter than standard concrete. This means it’s easier to move around and use in different ways.
Advantages of GFRC
Discover the amazing benefits of GFRC (Glass Fiber Reinforced Concrete), a game-changer in the construction industry. Renowned for its exceptional strength and durability, GFRC outperforms traditional concrete, effortlessly resisting cracks and weather damage. Its lightweight nature is a standout feature, making it easier to transport and handle, which is ideal for complex construction projects.
Architects and designers are drawn to GFRC’s versatility, as it can be moulded into diverse shapes and finished in various textures and colours, offering unparalleled creative freedom. Moreover, GFRC stands out for its environmental friendliness. It requires less cement, can incorporate recycled materials, and has an energy-efficient production process, aligning perfectly with sustainable building practices.
Lightweight Yet Strong
One of the most significant benefits of GFRC is that it is lighter than traditional concrete. This makes it easier to handle and transport, reducing construction costs. Despite being lightweight, it doesn't sacrifice strength, making it ideal for a variety of construction needs.
Design Flexibility
GFRC can be easily moulded into almost any shape and finished in different textures and colours. This flexibility is a big plus for architects and designers who want to create unique and intricate designs in their construction projects, opening up innovation possibilities.
Durability
GFRC is much tougher than regular concrete because the glass fibres mix into it and act like a strong network that holds everything together. This strength means that structures made from GFRC don't easily crack or break and can survive harsh weather conditions for many years.
Environment Friendly
GFRC is more eco-friendly than traditional concrete. It uses less cement and can incorporate recycled materials in its mix. Additionally, its production process is more energy-efficient. This step towards sustainable construction practices reduces the overall environmental impact.

Frequently Asked Questions
Key Elements That May Affect Your Mix
Cement: No two cements are the same, they have different mineralogies and different particle sizes. Cements from the same kiln will have a different particle size depending on the date and time of year made. Basically, finer particle size will increase the surface area and the plasticiser demand.
• Finer particle size will increase thixotropy, the amount of flow when being agitated. A higher thixotropy produces much less flow when not agitated.
• Sand: The size of your sand has a huge effect on the flow of your GFRC, a coarse sand will have a better flow than a fine sand. If your sand is very fine, it could make your mix unusable and solid. A coarse sand will have a lower water demand than a fine sand, and a wet sand has trapped water on the surface compared with dried sand. Controlling your mix, you should always take into account the level of water in your sand. To do this either use dried sand or dry your sand before you weigh it out.
• Temperature: The hydration of cement gets faster with increasing
temperature, roughly halving the work time every 10°C rise.
• Therefore, if the cement gels at 2 hours at 20°C, it will gel at about 1 hour at 30°C and 30 mins at 40°C. Adding ice changes the mix temperature and slows the get down, so always check your water and powder temperature.
How Much Ice Do I Need To Add To Mact Premixed Products?
- + 10° 20° 30°
- 0° N 12.1% 38.3%
- 1° O 13.7% 40.5%
- 2° 15.8% 42.4%
- 3° I 18.3% 44.0%
- 4° C 21.0% 45.2%
- 5° E 24.0% 46.2%
- 6° 27.0% 46.9%
- 7° 30.0% 47.6%
- 8° 10.6% 33.0% 48.2%
- 9° 11.1% 35.7% 49.1%
Amount of ice to add for any temperature. Always subtract the ice from your mix water.
10 kg of water with 50% ice would be 5kg water and 5 kg ice.
Note: If adding Ice, only add half your powder to the water/ice first to allow some of the ice to melt before adding the rest of the powder. Otherwise, your mix may gel prematurely.
