Fibre Reinforcement
|
Fiber reinforced polymer (FRP) materials have emerged as a practical and attractive material for producing reinforcing bars for concrete structures.
|
 |
FRP reinforcing bars offer a distinct advantage over steel reinforcement in that FRP bars are non-corrosive and non-conductive. In a market perspective it is first of all the non-corrosive nature of FRP reinforcement that is of significance. |
Provided properly designed, executed and maintained, steel reinforced structures are durable and long lasting structures. However for many structures subjected to aggressive environments, combinations of moisture, temperature and chlorides can reduce the alkalinity of the concrete and result in the corrosion of reinforcing and prestressing steel. Exposed in this context are e.g. marine structures, bridges and industrial structures.
Through our involvement in research into and the development of best practice for the use of FRP reinforcement, we have gained extensive experience in this new and innovative material and are able to offer our clients cutting edge designs to cater for all their aggressive environment needs. |

Floating fish farm
A floating fish farm may consist of a floating concrete tank made up of girders. Dimensions and equipment attached will vary. The fish farm may contain concrete silos for the storage of fodder, cold store, workshop and a room for human inhabitation. These are often placed in floating chambers or in a service building on top of the floating chambers.
The external walls are currently reinforced by using steel reinforcement nets with approximate dimensions ø12c150. Problems with corrotion often occur in the external reinforcement in the wave zone. Replacing this steel reinforcement with GFRP, will significantly reduce the risk of corrosion and maintentance costs.
