Abstract

The present work attempts to determine the
most suitable surface processing techniques and environment conditions to
reduce the slipping risk of pedestrians while walking barefoot and wearing
shoes on natural stone floor coverings. In this study, coefficients of friction
(COF) of surface-processed natural stones with three different methods were
determined by using DIN EN 51097, DIN EN 51130 and TS EN 14231 standards.
Coefficients of friction (COF) have been determined by using ramp test
equipment and a pendulum method on 15 different types of dimensioned-classified
rocks applied with polishing, honing, patinated and tumbling surface processing
techniques. It was found that the parameters that affected COF values of the
natural stones were environment conditions (wet, dry and lubricated) and the
applied surface processing techniques. The natural stones were then grouped
according to places for safe utilization depending on COF values and surface
roughness, according to the statistical results.

Doğal Taşların Sürtünme Katsayılarını (COF) Belirleyerek Yüzey Özelliklerinin Kayma Güvenlik Risk Analizi

Abstract

Çalışmada yalınayak ve ayakkabı ile yürürken doğal taş
zemin kaplamalarında yayaların kayma riskini azaltmak için en uygun yüzey
işleme tekniklerini ve çevre koşullarını belirlemeye çalışılmıştır. Bu
çalışmada DIN EN 51097, DIN EN 51130 ve TS EN 14231 standartları kullanılarak üç
farklı yöntemle yüzeyleri işlenmiş doğal taşların sürtünme katsayıları (COF)
belirlenmiştir. Sürtünme katsayıları (COF), cilalı, honlu, patinatolu ve eskitilmiş
yüzey işleme teknikleri ile uygulanan boyutlandırılmış sınıflandırılmış 15
farklı doğal taş üzerinde eğik düzlem testi ve pandül yöntemi kullanılarak
belirlenmiştir. Doğal taşların COF değerlerini etkileyen parametrelerin ortam koşulları
(yaş, kuru ve yağlı) ve uygulanan yüzey işleme teknikleri olduğu bulunmuştur. Doğal
taşların istatistiksel sonuçlara göre COF değerlerine bağlı olarak güvenli
kullanım alanlarına göre sınıflandırılmıştır.
