Correlations between the slip resistance and surface roughness of ceramic floor tiles

The characteristics of the floor surface profile are one factors that can be responsible for slip and fall accidents. To reduce incidence these accidents, it is essential to identify features necessary covering materials suitable slipping risk areas. objective present work was investigate correlations between resistance roughness ceramic tiles. commercial tiles, with a diversity finishes, were characterized by pendulum method contact profilometry, respectively. It concluded presence large number sharp peaks per unit length required high also found waviness contributes increasing floors even more. Through regression analysis, good correlation results parameter Ra found.
