DFRCC known as ductile fiber reinforced cement  composite was generated as a mend substantive structures have reinforced cement components. The ductile fiber cement reinforced composite is a concrete based substantive with cargo deflection toughening up behavior & elevated tensile force. This survey terminates boosting excitement zone of the reinforced cement plainly approved beams with ductile fiber cement reinforced composites layer made by mortars altered by 2% Polyvinyl alcohol (PVA) fiber and 1% Polyvinyl alcohol (PVA) solution. The thicknesses of DFRCC layers were 10, 20 and 30mm at tension zone that led to increase in the ultimate charge capability with approximately 7%, 11.5% & 15% and decrease in the middle span deflection at dysfunction by 18%, 36 % & 22% respectively. As well as to rise in elasticity file by 40, 48 and 62% respectively as compared with the reference beams. The experiment products demonstrated a reduce cracks wideness with higher amount cracks, and manner of damage of strengthened beams was observed by the flexural crack in zone of tension; whereas the reference beam loss was shears and flexural.
