Bamboo is known for its high tensile strength. However, the use of bamboo for construction material is hindered due to several factors, such as the ease of being attacked by fungus, termites and beetles, and also its irressistence to weather. The aims of this study is to investigate the effect of leaching of CCB4 preservative material on tensile strength of bamboo. For this purpose, the experiment was carried out on two species of bamboo, namely Petung (Dendrocalamus asper) and Legi (Giganthochloa verticillata). The experiment was initiated by preserving bamboo Petung and Legi using CCB4 preservative material with concentration of 0%, 5%, 10% and 15%. The preservated bamboo was placed on the open air for 0, 6 and 12 months to allow leaching process to take place. Each rod of bamboo was divided into 3 parts (namely bottom, middle and top). Tension test was carried out on bamboo specimens for every exposure period. Every test was repeated three times. Test results yield the average tensile strength of bamboo for leaching period of 0, 6 and 12 months is of 218.70 MPa, 207 MPa , and 198.1 MPa, respectively. In comparisson to initial leaching period there is a significant decline of average tensile strength of 5.1% and 9.2% , respectively.
