Next Generation : GFRC, GRC, Glass Reinforced Concrete
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:
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
Composition:
Both GFRC and GRC are made from a mixture of hydraulic cement, fine aggregates, water, and alkali-resistant glass fibres. The glass fibres serve to reinforce the concrete matrix, improving its tensile strength and resistance to cracking
Applications:
This material is widely used in architectural applications due to its lightweight nature and versatility. They can be molded into intricate shapes, making them ideal for decorative elements, facades, and structural components
Composition
GRC is made from a mixture of hydraulic cement, fine aggregates, water, and alkali-resistant glass fibres. The fibres enhance tensile strength and reduce cracking.
ShapeShell™-RC consists of Portland white cement or calcium silicate, reinforced with fibres. It also includes fine aggregates, oxide pigments, and functional additives for improved performance and aesthetics.
Manufacturing Process
GRC is typically produced by spraying or laying the mixture into molds designed to specific dimensions, with a thickness ranging from 15 to 25 mm.
ShapeShell™-RC utilizes advanced manufacturing techniques such as spraying to ensure uniform consistency and performance. This method optimizes resin flow during production, enhancing the material’s properties.
Performance Characteristics
GRC offers good durability and fire resistance but may not meet the highest standards for non-combustibility.
ShapeShell™-RC is classified as non-combustible under AS 1530.1 standards, making it suitable for heavy-duty architectural applications where fire safety is critical. It boasts a 50% increase in stiffness compared to standard GFRC, making it significantly more robust.
