Abstract
Abstract The paper presents an impact of the addition of industrial machining chips on the mechanical properties of polymer concrete. As an additional filler, six types of industrial waste machining chips were used: steel fine chips, steel medium chips, steel thick chips, aluminium fine chips, aluminium medium chips, and titanium fine chips. During the research, the influence of the addition of chips on the basic parameters of mechanical properties, i.e., tensile strength, compressive strength, splitting tensile strength, and Young’s modulus, was analyzed. On the basis of the obtained results, conclusions were drawn that the addition of chips from machining causes a decrease in the value of the mechanical properties parameters of the polymer concrete even by 30%. The mechanism of cracking of samples, which were subjected to durability tests, was also explored. In addition, it was found that some chip waste can be used as a substitute for natural fillers during preparation of a mineral cast composition without losing much of the strength parameters.

Comparing the average values of Young’s modulus, it can be noticed that the addition of steel fine chips (SFC), steel medium chips (SMC), and titanium fine chips (TFC) decreased Young’s modulus by about 20–25%, while the steel thick chips (STC) increased its value relative to the composite without the addition of chips (WC) by 28%
In the second part of the research, compression tests were carried out to determine the value of compressive strength and splitting tensile strength
Summary
Over the past ten years, the development of polymer concrete research has prompted their widespread use. A PC – polymer concrete (mineral cast), is a heterogeneous material, which consists of a filler in the form of natural grains of various aggregates and a binder in the form of a polymer resin, together with a hardener [1–6]. Polymer concrete is used for the production of various products, such as prefabricated sanitary devices, corrosion-resistant constructions, acid tanks, wells, drains, highway barriers, repair materials, railway sleepers, or machine parts, i.e., guides, tables, and machine tool beds [7–10]. Polymer concrete has very good dynamic properties; mechanical properties are characterized by low values of parameters.
