with the raise and continuous development of the concept that the buildings should be Energy-saving, environmentally friendly and greening, it has enjoyed a more widely use and has been used in a large amount in building roads, squares and pedestrian roads and so on. But its performance of permeability keeps falling down in the process of been used in years, which have a bad influence in its working life. At the same time it is determined that its performance should be improved by its bounded ness of ecological function. This experiment applies nanometer TiO2 on behave of Neon semiconductor catalytic materials to pervious concrete. It can not only meet the requirement about its performance durability in a certain degree, but also highly improves its ecological function.
