Abstract :

The rehabilitation, repair and strengthening of concrete structure has increased worldwide with a growing number of systems employing externally applied fiber-reinforced polymer (FRP) composites. For applications of structures, an overview of different FRP composites is provided by various polymer composites and in civil structures FRP composites are used for reinstatement or firming up the elemental constituent. This paper examines ability of a woven carbon fiber reinforced polymer faic wrapping to enhance the strength of various building components. Six concrete cubes of M20 grade and with dimensions of 15cm x 15cm x 15cm were casted for this purpose. Proper curing of 7 days for three cubes and 28 days for another three cubes was done. Later on compressive tests were carried out on these cubes using standard compression testing machine until the first crack appeared. The cubes were then wrapped with the carbon fiber faic of 300 GSM 12k unidirectional. Along with the cubes the same procedure was carried out on a column in a live building situated at Vani, a village near Nasik city. Non-destructive tests were carried out on this column and wrapping was done with the same grade of carbon fiber faic and further tests were carried out.
