Abstract
Composite materials for various purposes are made on the basis of initial mixtures of fillers and bonding components. The varieties of these components and their quantitative ratio determine the qualitative indicators of the composite. This causes rosettes of the raw material base for the production of composites, including the use of by-products of mineral extraction, which meets the objectives of resource saving.
 This paper presents the results of the study of composite materials on the basis of by-products of extraction of igneous rocks of Transcarpathia - siftings of andesite as a filler and copolymer Latex 2012 as a matrix. The analysis of chemical and mineralogical composition of andesite siftings from Khust quarry was carried out.
 An analysis of the dependence of the main physical and mechanical characteristics of the studied composites on the concentration of andesite in the range of 55-85 wt. % and of the corresponding change in the quantitative ratio of filler and copolymer is performed. Differences in parameters using andesite samples with different particle size distribution (the poly-fractional with particle size ˂ 3 mm and the dispersion one with particle size ˂ 0.5 mm) were determined.
 The peculiarities of the formation of the pore structure of the composite material obtained using andesite samples of different granulometry connected with the increasing degree of dispersion associated with the increase in the number of filler particles in the composite, increasing adhesion forces in the copolymer-filler system and increasing of surface energy of andesite particles are shown.
 The possibility of increasing the abrasive resistance of the composite material when using the initial mixture based on the andesite-copolymer system has been experimentally confirmed.
