Concrete and the Adaptive Mould is a happy mix, allowing for multiple different production setups and materials. Detailed information on the different processes and materials is available here and by contacting Adapa directly.
Glassfibre Reinforced Concrete (GRC), also known as Glass Fiber Reinforced Concrete (GFRC) is generally manufactured by either the sprayed or the premix process. Premix GRC can either be vibration compacted, or manufactured using a self compacting mix. The method chosen is normally dictated by factors such as strength requirements, size of mould, or architect’s specification.
As a general rule, larger items, such as building cladding panels, are normally sprayed whereas small items are manufactured using a premix GRC method.
Spray-Up GFRC refers to the process of using a spray pump, either rotor/stator or peristaltic, to spray a GFRC slurry and continuous strand AR glass fiber roving. It uses a specialized spray gun with an integrated fiber chopper. The GFRC slurry and fiber are fed to the gun separately and the chopper cuts the fiber and introduces it into the slurry stream at the spray nozzle.
Sprayed GRC is generally stronger than premix vibration cast GRC. The reasons for this are first and foremost that sprayed GRC is possible to achieve a higher fibre content. Secondly, sprayed GRC has a lower water content than premix GRC.
Premix GFRC incorporates AR (Alkali Resistant) glass fibers, or chopped strands, into the slurry during mixing and slurry preparation. The Premix process is further broken down into various production techniques such as spray premix, cast premix, pultrusion and hand lay-up. Premix is most often used for smaller GFRC parts and rarely incorporates a frame.
