ShapeShell™-RC (Reinforced Concrete)

GRC and GFRC Panels, Engineered Further: ShapeShell™-RC

What is ShapeShell™-RC?

ShapeShell™-RC in the next reinforced concrete, specifically designed for heavy-duty architectural applications, where fire safety and durability are critical. This substrate is classified as non-combustible under the AS 1530.1 standard, making it highly suitable for projects that demand stringent fire resistance. In addition to its safety features, ShapeShell™-RC offers a range of protective coatings, including advanced fluoropolymer and gel coat finishes, which enhance both durability and aesthetic appeal.

Product Composition 

ShapeShell™-RC essentially consists of the cement or calcium silicate formed by a chemical reaction of siliceous and calcareous material, reinforced by fibres. Those are: 

  • Portland white cement 
  • Reinforcing fibres 
  • Fine aggregate 
  • Mineral pigment and paint 
  • Functional additive 
  • Selected material filler proving extra smooth surface 

Production Method 

GRC or GFRG is batched and blended in accordance with industry standards using the specified mix design. Its mixture is sprayed and laid into moulds designed to match the shape and dimensions shown on the approved shop drawings. Where the thickness of the GRC 15-25 mm.

Product Appearance 

GRC or GFRG is a through coloured fibre cement panel with no coating. The product surface of the sheet is characterised by a textured surface. The board receives a hydrophobation which prevent moisture ingress into the core of the panel.  

Key Advantages

  • Advanced fibres in a cementitious matrix.
  • 50% stiffer than standard GFRC
  • Modern fibres in a geopolymer matrix.
  • 50% lighter than precast concrete panels.
  • Commingled nano raw-material additives and fibres.

Glass reinforced concrete (GRC, also called GFRC) is the material architects reach for when a facade needs the look and permanence of concrete without the weight. ShapeShell-RC is ShapeShift Technologies’ next-generation GRC: alkali-resistant fibres in a refined cementitious matrix with nano-scale additives, designed and manufactured under one roof from shop drawings to delivery. 

Why specify ShapeShell™-RC over standard GRC 

  • Non-combustible. Classified under AS 1530.1, suitable for projects where fire performance is a deemed-to-satisfy requirement, not a negotiation. 
  • Stiffer. Around 50% greater stiffness than standard GFRC, which means larger panels, fewer joints and fewer fixings per square metre.
  • A fraction of the weight of precast. Typical panel thickness of 15 to 25 mm delivers the appearance of mass concrete at a small fraction of the dead load of precast panels, reducing structure, transport and crane cost. 
  • Finish range. Through-coloured with off-form, oxide, exposed aggregate and PVDF coating options, plus hydrophobic treatment against moisture ingress. 

Where it is used 

Facade and cladding panels, screens and fins, soffits, column covers, heritage reproduction profiles, civil infrastructure elements and public artwork. Because the mix is sprayed or laid into CNC-machined moulds, complex curvature and free-form geometry cost far less than they would in precast.

FAQs

What is the difference between GRC and GFRC?

Nothing material. GRC (glass reinforced concrete) is the British and Australian term, GFRC the American. Both describe concrete reinforced with alkali-resistant glass fibres in place of steel. 

ShapeShell™-RC is classified non-combustible under AS 1530.1. Always confirm the specific product certificate for your compliance pathway; not all GRC on the market carries the classification. 

Typically 15 to 25 mm for ShapeShell™-RC, which is what makes the weight saving over precast possible. 

Yes. Spray application into CNC-machined moulds is the standard production method for complex geometry, and it is where GRC has the clearest cost advantage over precast.
