GRC is a compound material composed of white cement, fine aggregate, water, chemical admixtures, and alkali-resistant glass fibres. Glassfibre Reinforced Concrete (GRC) is a material that contributes significantly to the economy, technology, and aesthetics of the global construction industry.
This environmentally friendly composite, with its minimal energy and natural raw material consumption, is being shaped into a wide range of goods and has gained favor among designers, architects, engineers, and end users for its flexibility in meeting performance, appearance, and cost standards.
Applications of GRC
Glass fiber reinforced concrete is commonly used in the following building projects:
- Building renovation works
- Water and drainage works
- Bridge and tunnel lining panels
- Permanent formwork method of construction
- Architectural cladding
- Acoustic barriers and screens
Role of white cement in GRC
According to JK White Cement, GRC is currently driving the innovation and designs of the future.
GRC has always been at the forefront, contributing to innovation and creating future concepts. White cement-based GRC is not only durable, but also superior in terms of color, application, longevity, strength, aesthetic, and cost-effectiveness when compared to grey cement-based GRC throughout time.
White cement is now used in a variety of applications, including self-illuminating concrete, translucent concrete, and buildings that can be photo-engraved. Even in GRC, white cement has been used in a variety of applications such as cladding panels, fascia panels, decorative panels, arches, fountains, domes, and many more.
White cement has many advantages over grey cement including the fact that a white cement-based GRC does not decay as compared to Reinforced-Concrete Cement (RCC). Not to mention that the maintenance cost of white cement-based GRC is less as compared to grey cement-based GRC.
Benefits of GRC
- Lighter weight: With GRC, concrete can be cast in thinner portions making it up to 75% lighter when compared to identical parts produced with standard concrete.
- High strength: GRC has an extremely high strength-to-weight ratio and can have flexural strength as high as 4000 psi.
- Durability: Durability of GRC has been increased through the use of low alkaline cements and pozzolans.
- Sustainable: It uses less cement than similar concrete and frequently includes considerable amounts of recycled materials.
- Adaptability: GRC can adapt to nearly any complex shape, from rocks to fine ornamental details.
GRC manufactured from white-cement offers several benefits to creative concrete professionals, putting pressure on overall construction costs to be reduced. GRC delivers higher strength than RCC for the same membrane thickness, allowing experts to be more creative and aesthetic making it more successful.
