Porosity analysis of three types of balsa (Ochroma pyramidale) wood depending on density

Abstract Balsa ( Ochroma pyramidale ), which is the lowest density wood, a useful species in various industries. In general, balsa can be divided into three types (low density: LD, middle MD, high HD). this study, we classified porosities of through-pore porosity, blind-pore and closed-pore porosity. As result, total porosity showed positive (+) correlation with but negative (?) correlations Such information when using as natural porous material.
