“…[ 115 ] Some polymer concrete properties as strength, chemical or abrasion resistance, and adhesion can be improved when compared to Portland cement. Hameed and Hamza [ 116 ] have evaluated the incorporation of waste of concrete debris, ceramic tiles, and from building blocks as aggregates into unsaturated polyester resin. Mechanical properties were improved by resin incorporation when compared to Portland cement.…”

The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…The equations describing the course of dependence of surface layer parameters and tool wear from the depth of cut were also determined. For the Ra parameter, the equation describing the course of the curve took the form (7). As a result, Ra, Rz, and VB parameters can be determined for any depth of cut ap in the range from ap = 0.25 mm to ap = 2 mm.…”

“…Therefore, to obtain the appropriate surface layer parameters, the elements made of mineral cast must be machined after removal from the mold. An extensive description of polymer cements, mineral casts and resins used in the castings' processes of ceramic matrix composites has also been included in the scientific articles [3][4][5][6][7][8][9].…”

The paper presents the results of experimental determination of the Surface Geometrical Structure (SGS) parameters and tool wear during turning the polymer concrete. Until now, all literature reports have shown that the smoothness and roughness of the mineral cast surface was obtained directly from the mold. However, new applications of polymer concrete, even for some parts of the machine tools, forced the producers to carry out machining, which would improve the parameters of the surface layer. The topic of machining ceramic-based composite materials is a new chapter in the field of machining, which has not been sufficiently researched so far. The article describes the process of experimental determination of dependence of surface layer and tools wear parameters from cutting parameters during longitudinal turning of polymer concrete. The turning was carried out using plates made of a cubic boron nitride (CBN). After machining, the surface roughness and the maximum width of the flank wear were measured. On this basis, the mathematical model of the surface layer and tools wear parameters versus cutting parameters were defined. The authors also attempted to explain the phenomena occurring in the machining zone using variable cutting parameters. Microscopic pictures of CBN plates after machining were also performed. After the study, the final conclusions about the machining of mineral cast material were formulated.

“…Such materials include polymer concrete, which also appears under the name mineral cast. It is a complex material consisting of inorganic aggregates, such as basalt, spodumene (LiAlSi 2 O 6 ), fly ash, river gravel, sand, chalk, etc., bound with each other by resin [1][2][3]. The most commonly used resins are epoxy [4], polyester [5] and vinyl ester [6].…”

The paper examines the wear of end mill cutters, the parameters of a workpiece's surface layer and the values of cutting forces during the machining of polymer concrete, which is one of the most difficult-to-cut materials. Increased abrasive wear of the active cutting edges is a result of the heterogeneous structure of this material, and it has a negative effect on the cutting process, the durability of the cutting tools as well as the roughness of the workpiece. It is very important to determine the machining parameters for this material from a tool durability and quality of machining point of view. The research was divided into two stages. In the first stage, the appropriate machining parameters were determined based on the measurement of the components of the cutting force. In the second stage, durability tests of four end mill cutters were carried out. During the tests, the component cutting forces, tool wear and surface roughness were measured. The highest tool durability was recorded for the monolithic cemented carbide cutter with coating NC Mill G9F42120N 4F. Tools made of high-speed steel should not be used for machining polymer concrete, as they exhibited the highest intensity of tool wear. The rapid loss of machinability of these tools leads to a rapid increase in cutting force and the roughness of the machined surface. From an economic point of view, cemented carbide end mill cutters with coatings seem to be the appropriate choice for machining polymer concrete.
