| Popis: | Concrete is the most consumed material, with three tonnes per year used for every person in the world. Twice as much concrete is used in construction as all other building materials combined. Concrete has excellent characteristic in compressive strength, but low in tensile strength. Steel commonly used in reinforcing material because of high tensile strength. The usage of steel as reinforcing material is limited because it is costly and also has an effect on air pollution during its manufacturing process. As an alternative to overcome this problem, bamboo material has been used as a replacement of reinforcement in concrete. Bamboo is a suitable material because it is a natural material, cheap and also available material. In this research, the performance of bamboos as an alternative material in reinforced concrete has been evaluated. Tensile strength test of bamboos has been performed to identify the yields stress of bamboos. From the test, result has shown that bamboo has a similar characteristic with steel and bamboo can be used as an alternative material for reinforcing concrete. However, the characteristic of bamboos showed high water absorption and low bonding strength between bamboo’s surface and concrete. In this research, a waterproofing agent has been used to minimize water absorption and increase the bonding strength. Flexural strength test of the bamboo singly reinforced beam with the size of 150 mm x 150 mm x 750 mm has been undertaken to determine the performance of bamboo as reinforcement. From the test, it has resulted that bamboo give good potential as an alternative material in concrete reinforcement for low-cost housing industry. |
