What is GRC made of?

Compared to most other concrete and stone materials for construction, GRC is hands-down the most versatile and flexible option on the market to date.

Whereas many other alternatives work either for structural or aesthetic projects, GRC, also known as Glass Reinforced Concrete, can fit squarely in both categories as well as having a malleable nature that can allow it to shift and alter its shape far better than virtually anything else out there.

But why? What is it that makes GRC such a highly useful option for virtually all buildings?

What is GRC made of?

Compared to most other concrete and stone materials for construction, GRC is hands-down the most versatile and flexible option on the market to date.

Whereas many other alternatives work either for structural or aesthetic projects, GRC, also known as Glass Reinforced Concrete, can fit squarely in both categories as well as having a malleable nature that can allow it to shift and alter its shape far better than virtually anything else out there.

But why? What is it that makes GRC such a highly useful option for virtually all buildings?

GRC Cladding Components

The answer comes by way of its various material components, in particular, its glass fibres. Unlike other stones or cementitious mixtures, GRC is composed of sand, cement, water, several admixtures, and numerously dispersed short-length glass fibres. It is this combination that gives it the ability to work for both structural as well as non-structural projects, giving them equal parts lightness as well as impressively high tensile strength.

The Importance of Glass Fibres

Initially used only for non-structural building elements, GRC’s glass fibres, while always recognized for their incredible tensile and impact strength, were feared as being potentially not durable enough. Since the advent and development of several new and more durable types of alkali-resistant glass fibres, however, these fears have not only been entirely assuaged, but it has been found that GRC works considerably better in structural projects than other forms of concrete and cement!

Production Methods of GRC

There are two primary methods of producing GRC for building projects. For non-structural elements, such as cladding, GRC is applied via the “spray-up” method. In instances where it is required for fully structural projects, such as creating building foundations or pillars, GRC is premixed.

Spray-up Method

The process of spraying up involves combining the mortar components (the sand, cement, water, and other mixture additives) together before spraying out from a spray gun on the building site. In these instances, the glass fibres are not included and are actually mixed only at the end of the process at the jet of the spray gun. The full mixture is then allowed to mould over the intended structural site.

Because the glass is brought in at the very final stage of the process, the spray-up method is only meant for non-structural elements like cladding, pipes, and other small and non-plane elements. That said, this method is perfect for numerous exterior designs as well as offering the area different potential colour options.

Premixed Method

The premixed option, as the name implies, includes the glass fibres into the pre-mixture. The process is quite precise and is largely dependent on what is expected to be made using the mixture. It requires two separate stages before it is complete, both ideally performed in the same container.

The first stage consists of preparing a uniform addition of fibres for the mixture while the second stage consists of dispersing those fibres into the mortar mixture.

When premixed, GRC can work as an excellent structural-element alternative for other types of cement, stone, or concrete while retaining its lightweight nature and overall flexibility. It is because of this that so many people are looking to use GRC for their numerous housing and structural projects.
