Abstract

The experiment standard EN 14157 (Natural stones - Determination of abrasion resistance) is applied both as certification and in the context of quality assessment for natural stones. This standard presents the application details of “wide wheel abrasion” and “Bohme abrasion” tests used for determination of abrasion resistance of natural stones used as slabs in construction sector. The standard suggests the “wide wheel abrasion (Capon)” test as the reference method. In this study, the correlation between “Bohme abrasion (BA)”, which has been used for a longer time, and “wide wheel abrasion (WWA)”, which is relatively a newer method, is investigated. Limestone, marble, dolomitic limestone and travertine samples were collected from 21 different locations and both BA and WWA tests carried out on each samples. Data evaluated considered both weight (%) and volume (cm³) loss of Bohme abrasion test, separately. Regression analyses were performed and significant linear equations were found between WWA and BA test results.

Key words: Bohme, wide wheel abrasion, limestone, marble, travertine.
