Flexural Strengthening of RC Tee Beams using Ferrocement

Abstract

One of the cost-effective and most widely used methods of strengthening is the use of ferrocement lamination in the distressed element. In this investigation, 23 reinforced concrete Tee beams were tested for their flexural strength. Three sets of Tee beams were pre-damaged up to 60, 70, and 80 percent of the ultimate load level of control beams respectively. Beams pre-damaged up to 60% are designated as B1 and S1. Similarly 70% as B2 and S2 and 80% as B3 and S3. B1, B2 and B3 set (3 beams in each set) of beams were strengthened along soffit only using ferrocement. S1, S2 and S3 set (3 beams in each set) of beams were strengthened along with the side faces of the web only using ferrocement. After proper curing, all the strengthened beams were tested for their flexural strength. The results were compared with corresponding control beams and presented. Based on this investigation it is concluded that the flexural strength capacities of Reinforced concrete Tee beams strengthened with ferrocement are significantly increased.
