On the problem of rational use of sawmill waste: nanomodified wood-cement material on the basis of sawdust

 Abstract. The problem of rational use of sawmill waste is relevant for many years. Known technology use of sawdust in the production pellets, briquettes, building materials. However, the problem remains urgent. In Russia, volumes of dump sawdust are great. Contribution to the solution of the problem: can make use of sawdust as a basis for the production of nanomodified wood-cement materials with nanomodifiers. Realized studies in Petrozavodsk State University have shown that as effective modifiers may be nanoparticles of steatite. However, wood-cement mixes more effectively use an amorphous nanostructured micro-silica grade KOVELOS: additive 0.5% ... 0.7% by weight of cement M500 increases the strength of the cement-wood material 1.5 ... 2.1 times, depending on the manufacturing technology. Application for a patent filed.
Keywords: sawmill waste; wood-cement materials; nanomodifiers; interdisciplinary research; environmental management.
