Pavement in tunnels requires specific properties and functions. In this study, bright and slip-proof Engineered Cementitious Composites (ECCs) with visible light activated photo-catalysis properties are developed for pavement applications in tunnels. A carbon-modified TiO₂ is used to engage a visible light activated photo-catalysis property while white fine aggregates are included to enhance the skid resistance. With 20% silica sand and 5% TiO₂ inclusion, the resulting white ECCs possess excellent mechanical properties (i.e., compressive strength > 50 MPa, tensile strength > 4.5 MPa, and tensile strain capacity > 4%) and high skid resistance around 80 BPN, and has high surface reflectivity with a lightness value of 90. Furthermore, the resulting ECCs show strong visible light activated photo-catalysis property with 90% reflectance recovery after 4 h visible light irradiation and only 8% lightness reduction after the accelerated dirt pick-up resistance test.

隧道中的路面需要特定的属性和功能。在这项研究中，开发了具有可见光激活的光催化特性的明亮，防滑的工程胶凝复合材料（ECCs），用于隧道的路面应用。碳改性的TiO ₂用于实现可见光激活的光催化性能，同时包含白色细骨料以增强防滑性。使用20％的硅砂和5％的TiO ₂夹杂物，所得白色ECC具有出色的机械性能（即， 抗压强度> 50 MPa，抗拉强度> 4.5 MPa，抗拉应变能力> 4％）和80 BPN左右的高防滑性，并且具有高表面反射率，亮度值为90。此外，所得ECC显示出很强的可见光激活性可见光催化性能，可见光照射4 h后反射率恢复90％，加速耐污垢性试验后亮度仅降低8％。
