Glassfibre reinforced concrete rivals many competing products in weight and durability. Tipping the scales at significantly less weight than standard concrete, and still far less than lightweight concrete, its weight, or lack thereof, is one of its key benefits, making it easier to use and install.
It’s also a very malleable product, which opens the door for it to be used in anything from public artwork to the most ornate of historical restorations.
Key features of glassfibre reinforced concrete
“Glassfibre reinforced concrete is one of the most versatile building materials available to architects and engineers today,” GRC NZ’s Jamie Marryatt says. “It’s a composite material comprised of a mixture of hydraulic cement, silica sand, alkali-resistant glass fibres and water.”
The glass fibres reinforce the mortar mix, which improves its tensile strength and characteristics. “GRC was initially developed in the 1960s as a corrosion-free alternative to traditional steel-reinforced concrete and first manufactured as an exterior cladding material.”
