The purpose of this study was to evaluate the flexural performance of recycled aggregate RC beam reinforced with aramid fiber\nsheets. Compressive strength of concrete using recycled aggregate is generally similar or slightly lower than normal concrete. To\nimprove the compressive strength, aramid fiber sheets have been used in this study. This study examines the structural behavior\nof concrete beams prepared with recycled aggregate and strengthened aramid fiber sheets at varying locations. One concrete beam\nas a control specimen, that is prepared with 30 percent recycled aggregate and 70 percent natural aggregate, has been tested, and\n3 more strengthened beams (bottom, bottom and sides, bottom and both ends with U-shaped strengthened beams) are tested.\nThe ultimate loads have increased by 38.01%, 39.88%, and 100.79% for bottom, bottom and sides, bottom and both ends with Ushaped\nstrengthened beams.The ductility ratios are 2.75âË?¼6.20 for strengthened beams. The experimental results showed that the\nstrengthening system with U-shaped band controls the premature debonding and provides a more ductile failure mode than the\nstrengthening system without U-shaped bands. It can be found that the ultimate strength of H40-RGA30-BS specimen based on\nload-deflection curves shows most promising result.The experimental results are compared with the analytical results of nonlinear\nflexural behaviors for strengthened reinforced recycled aggregate concrete beam.
