Abstract

Various techniques are initiated for the strengthening of RCC beams to overcome flexural and shear. RCC beams are important load-bearing components in any building structure, but we should strengthen beams when material deterioration, defective design and accidental disasters occurred. In recent years the external bonding of steel plate technique is used for strengthening reinforced concrete beams, which is an effectual way to ameliorate the strength of the RCC beam. In this research 5mm, thick Mild steel plate is used for external bonding, M30 grade of concrete is used with various proportions of Manufacture and Natural sand. The research paper aims to differentiate the compressive, Split tensile and flexural strength of RCC beams with & without steel plates. From comparative results, it was found that the plate bonded beam observes more strength than no plate bonded beam at 50% replacement of M-sand.
