ABSTRACT

The study of the project is concerned with the investigation of properties of concrete by wrapping with glass fibre reinforced polymer sheet (GFRP). The use of GFRP is emerging in several applications in the construction industry, properties that are so different from those of steel. These applications are found evenly in structural concrete, architectural concrete, and masonry and both in new construction and repair and retrofits. These techniques can be adopted for rehabilitation of earthquake affected structures.

Many researches have shown that the introduction of glass fibre into concrete and their uniform disbursement give rise to higher strength like tensile strength, flexural strength, impact strength, resistance to cyclic loading etc. can be improved by the wrapping of concrete.

Cubes, prisms and beams was also cast for M20 grade of concrete. These specimens will strengthened with ISO branded GFRP wrap.

The properties of concrete with GFRP sheet wrapping was compared with those of the conventional concrete (concrete without GFRP wrapping) from the experimental investigation, it has been concluded that there is considerable improvements in compressive strength, tensile strength and modulus of rupture of concrete with GRRP wrapping.
