我國戶外常見以陶瓷面磚鋪設於騎樓或戶外步行空間，然而台灣地區氣候因潮濕多雨，常造成鋪面表面呈現濕潤易滑之狀態，導致使用者行走時產生滑倒的風險提高。故為確保步行者的行動安全，本研究計畫選用國內常用之陶質地磚、石質地磚及瓷質地磚共計20種樣本，並依據國家標準局所公布之操作流程與方法進行防滑係數之實驗，一方面瞭解上述材料於乾燥、潮濕狀態下之物理性能，另一方面針對實驗結果提出未來規劃設計戶外（或半戶外）空間時之材料選用建議。本研究測定「C.S.R」（穿鞋時之防滑係數值）防滑係數值，其防滑係數值平均介於0.471～0.771之間。

The ceramic tiles used to be commonly used on the veranda or outdoor walking space in Taiwan. However, due to humid and rainy climate, often causing slippery wet pavement surface rendering of the state, resulting in increase the risk of slipping when the user walks. Therefore, to ensure the safety of pedestrians action, this research project selected ceramic tiles, stone tiles and porcelain tiles a total of 20 kinds of samples, and non-slip based on operational processes and methods published by the Bureau of Standards, Metrology and Inspection, Ministry of Economic Affairs, to understand of these materials in a dry and humid state of physical properties, on the other hand provides some floor materials for planning and design of outdoor or semi-outdoor space as a suggestion. This study measures the average COF (Coefficient of Friction) of CSR (Coefficient of Slip Resistance) is between 0.471 and 0.771.
