Abrasion parameter of natural stone for public infrastructure and correlations with other properties

Abstract

The abrasion resistance is one of the crucial parameters to consider when evaluating natural stone for use in public infrastructure with light traffic. The assessment and evaluation of abrasion parameters can be carried out according to the EN 14157 standard, using two typical natural stones from different sources in order to compare the necessary parameters. The parameters will be analysed in correlation with other factors in order to find optimizations. The results showed a significant correlation coefficient between the dry sample and water saturation tests. This suggests that the abrasion resistance of natural stone when dry is closely related to its resistance when saturated with water. This information is valuable in selecting appropriate natural stone materials for public infrastructure, as it provides insights into how the materials will perform under different conditions. In public squares, natural stone is often used as paving material because of its durability, resistance to weathering, aesthetics and other parameters. However, different types of natural stone have different levels of abrasion resistance, which can affect their suitability for use in public squares.
