Abstract
In today developing construction field several alternates are being introduced for natural resources used in reinforced concrete. This project focuses on the alternate reinforcement for the structural members. The conventional reinforcement is replaced by the composite reinforcement. The composite reinforcement is in-filled with mild steel pipe which includes the cement slurry and sieved crumb rubber . This crumb rubber constitutes to the solid waste management. Hence these composite reinforcements will reduce weight of steel in reinforced concrete along with the reduction in cost of construction. The hollow steel pipe is madeup of mild steel and the local buckling of the steel pipe is delayed by the restraint of the concrete, and the strength of concrete is increased by the confining effect of the steel tube and crumb rubber.The rubber is collected from scrap tires. The scrap tires are made into crumb rubber and mixed with water – cement in a ratio to attain the colloidal consistency. The present experimental investigation is about the comparison of the flexural strength of concrete beam with conventional and composite reinforcement.
