Concrete Renovations Ltd offers the service of structural strengthening using resin bonded carbon fibre plates.
These carbon fibre plates are being installed by Concrete Renovations Ltd at Cambridge University’s Arup Building at the new museum site. In this case the concrete being strengthened is cantilevered requiring the plates to be placed on the top surface of the slab using epoxy resin adhesive.
Recent developments in material technology have seen the introduction of carbon fibre plates, which are significantly lighter and easier to install than steel plates of similar capacity.
Carbon fibre fabric is now also used to strengthen columns and beams using a wrapping technique. Single or multiple layers of uni or bi-directional fabric are impregnated with resin adhesive and applied to sections such as beams and columns to improve strength.
Since the late 1980’s there has been a lot of pioneering work in many research and testing facilities around the world, that resulted in huge advances in structural strengthening techniques, particularly with composite carbon fibre reinforced plastic (CFRP) extruded plate and woven fabric systems.
The bonded CFRP systems used by Concrete Renovations Ltd are specifically designed for use as ultra-lightweight but extremely high strength and durable external reinforcement, which is bonded to the structure with high performance epoxy resin adhesives.
This plate bonding system is also totally corrosion resistant and provides a long term maintenance-free solution, yet it is often incredibly cost effective versus traditional steel or additional reinforced concrete strengthening and rebuilding options for the owner.
