white poplar (Populus alba L.), physical properties, mechanical properties, pith to bark distribution

Sažetak
Investigation of physical and mechanical properties of wood are important for application of wood as a raw material. Nowadays, large quantities of wood from fast- growing species, especially from agricultural unusable land, are available on the market. One of them are poplars. The available data on physical and mechanical properties of white poplar wood grown in Croatia are insufficient. In this paper, some of this properties were investigated on white poplar wood (Populus alba L.) from the region near Varaždin. As well, the distribution of this properties from pith to bark was investigated. This preliminary study was carried out on five trees, using only segments with north and south orientation in the wood at breast height. This paper presents charts of listed properties from pith to bark for trees where the correlation of properties was greatest. The average values of results in this preliminary study are: density in absolute dry condition is 0, 413 g/cm3, density at 12% of moisture content is 0, 429 g/cm3, static bending strength is 62, 5 MPa, modulus of elasticity at static bending is 5, 2 GPa, compression strength parallel to grain is 34, 3 MPa. Correlation between properties in some trees was satisfactory, but in order to determine statistical reliability, research must be continued on larger number of samples.
