Abstract

Abrasion resistance is a property of a marble which gives an indication of the marble wearing quality when it is exposed to foot traffic. This property is tested according to ASTM C241 standards. Abrasion further helps in determining whether a marble is economically desirable and practical for floors, stairs, etc. For this, 48 samples were selected from different processing units of Rajasthan and were tested. Regression analysis was carried out to investigate the relation between the abrasion resistance and the mechanical properties of marbles determined according to ASTM standards. Although, it is believed that abrasion resistance of many materials are greatly affected by its hardness and it increases with the increase in the hardness. The correlations of abrasion resistance was found to be highly related with mechanical 2 2 2 properties like modulus of rupture (R = 0.96), compressive strength (R = 0.94), flexural strength (R = 0.96) along with 2 2 2 hardness (R = 0.84) while the water absorption (R = 0.08) and density (R = 0.44) were found to be less correlated.
