Abstract
Construction industry is the main consumer of energy and materials in most countries. Concrete is the most consumed construction material in the entire world. Concrete is found to have excellent compressive strength but poor in tensile strength. To take care of the tensile strength steel is commonly used reinforcing material. Due to the increasing cost, unavailability and other drawbacks of the steel enforced to use an alternative material as reinforcement. The use of bamboo which is fast growing and ecologically friendly material for structural applications is being considered as quite appropriate. The tensile strength of bamboo is quite high and can reach up to 125 MPa. The use of bamboo as a structural element may contribute to the reduction of material-based energy use of a structure. To investigate the feasibility of using bamboo as a reinforcing material in reinforced-concrete members, flexural Strength were carried out on reinforced-concrete beams in which all rebars, including the main rebar and the stirrups, were replaced with bamboo. In this present study nine beams each of size 150x150 x750 mm were cast to study the flexural strength. Beams were tested in flexure under two equal concentrated loads each applied at the one third point of the beam with the help of hydraulic jack. From these experimental works, it was concluded that bamboo can be usedin non-structural element in low cost construction.
