Improvements of reinforced concrete beams against the impact of torsional forces are among the most researched issues in construction studies. In this paper, repairing and strengthening the reinforced concrete beams using ferrocement laminates attached onto the surface of the beams and exposed to torsion were reviewed. This study aims to reveal the efficacy of the wrapping by ferrocement laminates. Experimental studies of previous researches were conducted by using SBR as a slurry for strengthening beams by ferrocement from two and three sides wrapping. Alternatively, the convenience of using SBR as an ingredient of the mortar on the performance of strengthened beams under torsion was discussed. The results showed that ferrocement is a practical alternative strengthening component for rehabilitating and repairing reinforced concrete beams. It was demonstrated that three sides wrapping is much more effective in improving the torsional behaviour in comparison with two sides wrapping. Also, the SBR preserved the joining until failure for the all strengthened beams.
