EXPERIMENTAL AND THEORITICAL ANALYSIS OF THERMAL PROPERTIES IN ZEPHYR BAMBOO TALI (GIGANTOCHLOA APUS KURZ)

Edit
Abstract: Specific heat, thermal conductivity and thermal diffusivity of Bamboo panel are usable to support  the Programming of Design and Planning in the Structure of the Agricultural Building Construction. The Specific heat of Bamboo’s fiber, sheet and panel using the method of mixtures varied from 1.585-2.789 J/gr oC, with a mean value of 2.227 J/gr oC in the temperature difference range of  9 ± 0.1oC . It was found it will increase linearly with an increase in the sample temperature. Thermal conductivity values of Bamboo’s fiber based on the transient line heat source technique varied from 0.1035 x 10-3-0.1322 x10-3 J/ cm2 sec oC in the sample temperature 22 to 30 oC on thermal diffusivity of bamboo fiber in 22-30 oC was found to be 0.0823 x 10-3J/cm secoC.   The sorption Isotherm and the water activity in the bamboo’s panel is depend on the chemical composition, glue laminated, additive and the porosity. There are related with the absorbing of the water into the bounded water and the diffusivity of the water in and out the panel. The moisture equilibrium range are 7.89 to 19.22 percent in the control of the circumstances and 11 to 75 % of  the environment.relative humidity.
