INFLUENCE OF THE SHARE OF WOOD FILLER AND MAGNESITE ON THE STRENGTH OF COMPOSITE
Abstract and keywords
Abstract (English):
Research in the field of creating new composite materials, including those based on magnesia binder and wood shavings – wood raw material - plays an important role in solving strategic tasks of construction complex development. Differences in the shape, size, and fractional composition of chips and wood shavings, which is used in the manufacture of the material-analogue (arbolite), determine the need to substantiate the composition of mixture main components. According the research, we obtained the relationship between the strength properties of wood-mineral composite (WMC) and the proportion of wood filler in the structure of the material. The study revealed relation of change in the compressive and bending strength indices of WMC with increasing mass content of wood shavings. It is recommended to maintain the ratio of wood shaving : magnesia binder at the level of 20 : 80, taking into account the intensity of strength properties change in the development of rational WMC composition.
