STRENGTHENING OF PLAIN CONCRETE MEMBERS USING FRP TECHNOLOGY

Ranganath T V L, Raghu Yadav.G

Abstract: Fiber Reinforced Polymer (FRP) is a composite material made of a polymer matrix reinforced with fibers.FRP materials posses’ superior mechanical properties like ability to carry loads, impact resistance, strength and stiffness. E-glass and carbon fiber FRP were selected for the present investigation. About 21nos. of plain concrete column specimens, 6 nos. of plain concrete beam specimens along with 4 concrete cubes were tested. M 20 grade of concrete was used to cast the above specimens. Single wrapping and double wrapping were the parameters for column specimens and wrapping in flexural zone only and wrapping in flexural zone and U clamp were the parameters for the beam specimens. The columns were tested for their compressive strength while the beams were tested for their flexural strengths under two point loading systems. The present investigation is to compare the enhancement of strength of plain columns and beams with E-glass and Carbon fibers

Keywords: Fiber reinforced polymer, E-glass, carbon fiber, single wrap, double compressive strength, flexural strength.
