Experimental study on bamboo hygrothermal properties and the impact of bamboo-based panel process

To obtain bamboos' material parameters and clarify the modification impact of bamboo-based panel (BBP) process, nine test items are carried out on six typical bamboos for hygrothermal properties, based on the building envelope heat and moisture process model. Results show that macroscopically gaseous water and heat storage properties show insignificant correlation with basic properties. Both moisture and thermal transport properties show stronger correlation with open porosity than with bulk density and are affected by moisture content to varying degree. Comparison between five BBPs and flattened raw bamboo show that the BBP process improves homogeneity and broadens the material properties spectrum. The transport properties are changed greater than storage properties in terms of both hygric and thermal aspects.
