摘要：At present, concrete and steel are the most widely used construction materials in the world. The concretehas high compressive strength but low tensile strength. Therefore, steel is used to reinforce the concrete. Steel has avery high tensile strength as compared to concrete, but there are certain problems associated with it. Some of theseproblems are high production cost, large energy consumption during its production; it is a non-renewable resource andlarge amount of carbon emission during its production. The urge to overcome these problems without the tensilecapacity of reinforced concrete being compromised, has prompted numerous scientists and engineers to seek out locallysourced materials as a replacement for conventional steel reinforcement. Specifically, bamboo is one of the mostsuitable materials that may be used as reinforcing bar in concrete. This project work assessed the suitability of bambooas reinforcement in concrete.Concrete mix for M-25 grade concrete has been found as per design requirement of the IS code 10262-2009. In thisproject, two size of beams were selected, which are 150 x 150 x 700 mm and 150 x 200 x 700 mm. Plain cementconcrete (PCC) beam, bamboo reinforced concrete (BRC) beam, treated bamboo reinforced concrete (TBRC) beam andsteel reinforced concrete (SRC) beam were casted for each size of beam and they were tested on flexural testingmachine. The samples included 6 beams for each type of beam.Area of reinforcement was kept same in steel reinforced concrete beam (SRC), bamboo reinforced concrete beam(BRC) and treated bamboo reinforced concrete beam (TBRC) for both the size of beams. The reinforced materialBamboo sticks, treated bamboo sticks and Fe 415 grade of steel were used for reinforcing in BRC, TBRC and SRCbeams respectively. The bamboo sticks were seasoned for about 2 to 3 weeks and then they were used asreinforcement. The flexural test results showed that steel reinforced concrete beam had the highest flexural strengthcompared to others. However, bamboo reinforced concrete beams (treated and untreated) showed a significantimprovement in their flexural strength as compared to plain cement concrete beam. Hence, it can be recommended touse bamboo reinforced concrete beam for light load bearing structures like beam and slab for small panel. Also, it maybe used for temporary structure.
