Abstract

Barking waste at a pulp and paper mill can be used for construction materials fabrication. The paper presents principles of an estimation technique based on image analysis of the surface for assessing wood-cement composites properties. Images of side faces of wood-cement composites samples obtained under certain lighting parameters are characterized by optical density anisotropy. Analysis of fractal dimensions of images of top, bottom, and side faces surfaces shows that their structure depends on the molding process of a wood-cement composite. The results obtained allow us to hope that a method of nondestructive testing the sample strength of such materials could be developed in future.
