Glass Reinforced Concrete
What's in a name?
Before we delve into the detail of exactly what it is, it is worth noting a number of different ways the material can be refereed to - Glass Reinforced Concrete (GRC), Glass Fibre Reinforced Concrete (GFRC), GFRC Concrete, Fibre Reinforced Concrete, Lightweight Concrete.
While the name can sometimes be interchangeable the fundamentals of well manufactred GRC remain the same.
GRC is Lightweight & Strong
Glass Reinforced Concrete (GRC) is fundamentally a concrete mix.
GRC differs from traditional concrete by adding the following raw materials to gain strength and reduce weight to the concrete mix:
- Alkaline Resistant Glass Fibre.
Typically manufactured to a thickness of around 12 to 15 mm, GRC is generally 50% - 70% lighter than precast concrete products. This is where the term lightweight concrete comes from.
A great advantage of this lightweight concrete manufacturing technology is that relatively large and strong moulded GRC products can be produced without being too difficult or costly to move around or transport.
GRC is Durable
The weathering characteristics of Glass Reinforced Concrete (GRC) are as good as any precast concrete and better than almost any semi-dry material for outdoor applications. The components of GRC can be specially formulated for greater protection and durability, with a wide range of specialised products that offer resistance from impact, weather, water, chemicals and fire damage.
Unlike traditional reinforced cement, GRC is not at risk of corrosion because it typically doesn't require steel reinforcement.
Unlike products moulded out of resin-based substances, GRC does not break down in harsh weather conditions or as a result of UV rays.
Unlike fibre clay pots and planters, GRC does not breakdown when in constant contact with wet soil.
Satu Bumi uses two highly tested and proven colouring techniques to suit various different product applications:-
The first colouring technique entails the use of an oxide wash whereby the colour is infused into the body of a product during the curing process. This process ensures that colour attributes maintain their integrity by resisting UV breakdown and by eliminating peeling in the harshest of weather conditions.
The second colouring technique entails the use of high quality paint that has been specifically developed for use on concrete surfaces.
GRC is Versatile
Glass Reinforced Concrete (GRC) offers an unrivalled creativity and versatility in the development of new product designs with its attribute of being able to be used to accurately reproduce almost any small or large product design. In addition, end products can be finished in a wide variety of textures and colours.
