“…These values indicate that artificial stone is 448% more resistant to abrasion than natural stone, commercialised on a large scale. Another study involving artificial rocks, based on granitic rocks, found little variation in resistance, ranging from 1.13 mm (natural rock) to 1.46 mm (artificial rock), in a cycle of 1000 meters (GOMES et al, 2021), demonstrating a greater performance gain in the composite developed in this study. This gain in abrasion resistance occurs due to the presence of the resin that has greater mechanical strength.…”

“…These stones can be formed by a high content of natural aggregates and a low content of polymeric binder in their composition, presenting good mechanical properties and low porosity, compared to natural stones (RIBEIRO, 2015). Da Cunha Demartini, Rodríguez and Silva (2018), Gomes et al (2021) and Shishegaran et al (2022) proved the technical feasibility of producing artificial stone from the agglutination of resin and rock wastes, showing that this stone can be a technically, economically and ecologically viable alternative.…”

Exploiting laminated limestone from Cariri Ceará for ornamental and coating purposes has generated about 2.9 million tons of waste, which is discarded of improperly, making it important to search for alternatives to this material. Thus, this work aims to develop artificial stone for wall and floor coating, using laminated limestone waste (Cariri Stone) and a polyester resin. Initially, Cariri stone waste was characterised, and then artificial stone was made with 25% resin and 75% waste, by volume. Water absorption tests and resistance to compression, flexion, abrasion and hard body impact were performed on the composites produced. The results showed that the artificial stone presented water absorption about 5 times lower and abrasion resistance 448% higher than the natural stone, compressive and flexural strength 38.8% and 72.9% lower than the natural stone, respectively, and energy values equivalent to the commercial natural stone in the hard body impact test. It can be observed that the composite produced has a technical potential for use as a coating in civil construction, after adjusting the production process of the artificial stone.

“…they found that epoxy granite composite with resin ratio between 60% to 70% is the most suitable composite for structural and engineering applications like machine tools structure. Maria Luiza et al [11] showed that epoxy granite composite had satisfactory physical and mechanical properties, like resistance to temperature oscillations, and high resistance to wear and impact. Selvakumar et al [12] carried out numerical, analytical, and experimental studies on specimens of steel, cast iron, and epoxy granite at constant stiffness to compare the properties of structures from these materials more precisely.…”

In Egypt, large quantities of coarse granite wastes are produced annually during the quarrying operations of granite rocks. This waste represents a potentially useful source of material for a variety of applications such as a filler material in epoxy granite composite material. In this work a new eco-friendly composite material studied as a substitute for machine tools traditional materials, like cast iron, to produce better efficiency with lower cost. This study aims to investigate the mechanical properties of granite epoxy composite by using the local epoxy (kemapoxy 150) and the granite residues in the Egyptian quarries. The investigated processing variable was epoxy content, and the mechanical characterization ware carried out by compressive and flexural tests according to the ASTM standard method B. Commercially available, Aswan red granite was procured, crushed, and sieved to three size ranges from 0.150 to 8 mm, respectively. Epoxy ratios of 80:20, 85:15 have been used with granite aggregate size mix with small, medium, and coarse size proportions of 50:25:25 respectively for preparing the specimens with granite granular size range (0.150-8) mm. The results show that Epoxy granite composite with granite to epoxy ratio of 80:20% wt. induced the highest compressive strength (72.15 MPa) while the composite with the ratio of 85:15% wt. induced the highest flexural strength (20.1 MPa). Epoxy granite composite show superior results with respect to cement concrete, polyester concrete, and natural granite.

A new multifunctional composite material manufactured from vinyl-acrylic resin and mixed with battery waste powders containing graphite, manganese oxide, and zinc oxide particles has been developed. The battery waste (BW) was obtained from a recycling company as a byproduct from the grinding process of primary batteries (alkaline and zinc carbon batteries). In addition, 24 and 28 AWG copper wires (CuW) were obtained from recycling circuit waste, which were added in 5, 10 and 15 wt% contents to form composite materials, with all CuW of 2 mm length. These formulations were characterized using scanning electronic microscopy, compression, density, and piezoresistivity tests. When copper was added to the composite material, the behavior of the sensor was linear, a characteristic desired in piezoresistive sensors since they do not need any additional configuration to obtain said linearity. As the percentage of copper increased, the sensitivity of the sensor decreased and the conductivity increased.
