The present invention discloses a bamboo reinforced concrete beam (100)
comprising: a plurality of bamboo splints forming a top (102) and bottom
reinforcement; a plurality shear links for shear reinforcement (106); concrete; and a plurality of steel wires for joining the plurality of bamboo splints. The plurality of bamboo splints (102,104) and the plurality of shear links (106) are fabricated from bamboos which are chemically treated with a combination of alkaline solution to mitigate fungus growth and black oxide primer to provide water repellent properties and to protect the bamboo splints against insect infestation. Further, a bamboo fibre reinforced concrete beam is disclosed. The bamboo fibre reinforced concrete beam comprising chemically treated bamboo fibres; cement mix; fine aggregates; coarse aggregates; and water. The bamboo fibres are extracted from plurality of bamboo splints which are chemically treated with a combination of alkaline solution to mitigate fungus growth.
