Description Concrete structures deteriorate with time, a process that becomes much faster in aggressive environmental
conditions. Broadly, methods to repair them can be classified under structural repair and nonstructural repair.
Structural repair is carried out by repair, renovation and retrofitting of the entire system as a whole for structural
strengthening to carry additional loads or for retrofitting. In the present work, attempt is made to study and
compare the effects of Glass fiber reinforced polymer (GFRP) wraps on the behavior of reinforced concrete (RC)
beams through experimental investigations. The experimental study consists of casting of four sets of reinforced
concrete (RC) beams having cross-sectional dimensions of 150mm x 200mm and 1000mm length and of grade
M30. , Total 48 no. of RC beam are cast and curing for 28 days. First set of (3 no.) RC beams designated as
control RC beams (SET I). Second set of (9 no.) RC beams (SET II); all are strengthened using single GFRP mat
wrap, (for three beam both side wrap, three beam bottom wrap and three beam (U) shape wrap), Third set of (9
no.) RC beams (SET III); all are strengthened using Double GFRP mat wrap, (for three beam both side wrap,
three beam bottom wrap and three beam (U) shape wrap). Fourth set of (9 no.) RC beams (SET IV) are
strengthened using Woven Roving GFRP mat wrap, (for three beam both side wrap, three beam bottom wrap and
three beam (U) shape wrap).
