Hard inorganic particles in the interaction with polymeric materials increase wear resistance. Also reactoplastics are suitable for filling with micro- and nano-particles for a purpose of some mechanical properties optimization. The paper compares chosen mechanical properties - hardness, wear resistance and tensile characteristics of epoxy resin filled with artificial corundum with various middle particles sizes and their ratio combination. Mentioned systems can be used in a sphere of the agricultural production at renovation of machine parts, they can serve for creating resistant layers on machines, floors and grillages at the same time. The aim of the carried out experiment is to compare the properties of reactoplastics filled with a primary and secondary raw material and to define an optimum ratio of the filler particle size relating to a given mechanical quality. The artificial corundum was chosen as the primary material, the waste corundum from the process of material mechanical treatment was chosen as the secondary one.
