Cracking behavior of sea sand RC beam bonded externally with CFRP plate

CFRP is an alternative technique for cracking control of high-chloride reinforced concrete (RC) beams. This research, therefore, investigates the strength performance and failure mode behaviour RC beams incorporated with sea sand bonded externally carbon fibre polymer (CFRP) plate. Sea used as a 100% replacement fine aggregate. Three batches were carried out in this including beam (no neither CFRP), normal plate, CFRP. A four-point bending test was performed under static loading specimens. Finite element simulation modelled further comparison. The experimental findings showed that flexural capacity plate 5.50% greater than without (control beam). Besides, results demonstrated failed by end debonding (PED) while bonding at mid-span crushing. However, stiffer, which could lead to lower crack spacing. very acceptable compared results.
