Fibre Reinforced Plastic/Polymer (FRP) are commonly used to increase the strength and elasticity of existing construction materials. The composition of polymer and fibres allows it to have its unique property and provide solutions to the ever growing concerns regarding cost and structural stability of beams & columns.

FRP strengthened reinforced concrete (RC) are used to improve and withstand loading pressure which in some occasion can lead to severe deformability and cracking. With this in mind it is crucial that we understand and apply the most effective technique to achieve structural rehabilitation. The steady move from steel reinforcements to fibre set a new evolution in civil engineering. By tackling the problem of steel corrosion and limiting the long term cost, FRP is considered are suitable materials for concrete structures.

The mechanical properties of FRP are determined by the amount and type of underlying fibre used. The primary material used is referred to as the matrix. This is a form of plastic which is weak and unsuitable when used as the core material. The matrix is often reinforced by stronger and stiffer reinforcing fibres, which are Carbon, Glass or Aramid.

In this project we set to investigate the elasticity and long term impact of FRP concrete under internal and external reinforcement. Using existing reports and raw data we aim to analyse the process involved to improve the degree of strength and elasticity behaviour.

Whilst the main properties are studied to a greater depth we will also focus on the limitation factors associated with FRP reinforcement. Structural failure from over/under loading, recycling issues and exposure to aggressive environment will be areas to focus when determining its true potentials when used in large scale.

OBJECTIVES

The aim of this research is to investigate the elasticity and long term impact of FRP concrete under internal and external reinforcement. By applying different techniques we focus on how the characteristics may vary and affect its functionality.

METHODLOGY

In order to achieve the set objective the following steps will be undertaken:

* Collect information about FRP materials to compare different size and types of reinforced bars and columns

* Collect data from laboratory test report to analyse the long term behaviour of concrete under internal and external reinforcement

* Collect data from laboratory report and analyse previous research

CASE STUDY

* Investigate the use and scale of FRP reinforcement within the construction industry. Analyse on the economical and other factors which are considered

* Analyse collected data from previews laboratory report
