The effect of physical and mechanical properties on the abrasion resistance of artificial stones produced with granite waste

The recycling of mine stone waste has been interesting for the creation of employment opportunities and added value and the prevention of environmental pollution. The present study examined the effects of the physicomechanical properties on the abrasion resistance of artificial stones produced with granite cut waste. A total of four artificial specimens were produced under different compositions and methods. Their physicomechanical properties, such as density, porosity, water absorption, hardness, compressive strength, and abrasion resistance, were evaluated. Finally, the artificial stones were compared to natural granite and marble in abrasion resistance. It was found that an increase in the porosity and water absorption reduced hardness, compressive strength, and abrasion resistance. Furthermore, hardness, compressive strength, and abrasion resistance declined as the porosity and water absorption increased. The increased rotational speed and load in the Taber abrasion test diminished abrasion resistance. The epoxy resin-based artificial stone exhibited the highest performance among the artificial specimens. It had almost the same porosity and water absorption as natural granite and marble. However, the epoxy resin-based stone with lower Mohs hardness and compressive strength showed less abrasion resistance compared to the natural granite and marble. As a result, all four artificial stones showed satisfactory performance for the flooring of congested areas.
