AbstractAbout AuthorsReferences
An analysis of literature data shows that the bark of conifers is the most suitable for wooden building materials as its composition has a significantly low content of easy hydrolysable substances (hemicellulose, non-cellulose polysaccharides). The article presents the data on the composition of the material with the use of pine bark and its water extract, principal technology for producing the composite without using mineral binders, and possibilities of its application. Experimental studies of the process of extraction of extractive substances from vegetal resources on the example of pine bark have been conducted; experimental samples of a composite material have been obtained; tests of obtained experimental samples for strength, heat conductivity, water absorption, and swelling have been carried out. The material is characterized by sufficient mechanical strength, a satisfactory value of heat conductivity factor, high ecological purity. The value of water-physical, heat insulation, and mechanical characteristics makes it possible to recommend it to use as non-structural heat insulation.
