The life of bamboo tree is usually 20 to 100 years.
To counteract this steel is used as a reinforcement material to gain tension. When structures have to be constructed on challenging ground conditions, soil reinforcement can be an adaptable technique to improve ground. The main obstacle for the application of Bamboo as a reinforcement is the lack of sufficient information about its interaction with concrete, strength and durability. Researchers are working on bamboo as a substitute to steel reinforcement bamboo reinforcement pdf in concrete. When bamboo is used as lateral tie reinforcement, the ties should be spaced not over 16 times the least dimension of the vertical reinforcement nor farther apart than the least dimension of the column. The bamboo reinforcement rammed earth wall building technology comprises a rammed earth wall body and bamboo reinforcements, and during the conventional rammed earth building construction, the bamboo reinforcements are arranged on the cross section of the wall body according to proper reinforcement ratio, so that the shock strength of the wall. Bamboo reinforcement should not be placed less than 1½ inches from the face of the concrete surface. Bamboo, if left untreated, can swell with bamboo reinforcement pdf water and rot.
Though bamboo has been used as a construction material, especially in developing country, until today its use as reinforcement in concrete is very limited due to various uncertainties. Job Creation 171 Bamboo Craft 173. Spacing of the stirrups should not exceed 6 inches. Bamboo Housing 137 Social Aspects 138 Technical Aspects 145 Guidelines for a Housing Project 163 10. this, 3–4% bamboo reinforcement is added resulting in, they claim, a factor of safety on the order of 2–2.
