Design and Application of Mix Proportion of Fully Recycled and Pervious Cement Concrete for the Haze Removal Pavement

Based on the fact that when fully recycled permeable concrete on the haze removal pavement be loaded with its raw materials, it will be strengthened at the same time. The preparation of cement slurry with silicon-coated nano-titanium dioxide not only makes the permeable cement concrete have the effect of degrading nitrogen oxides, but also improves its strength and frost resistance. Taking the influence factor of the permeability coefficient and strength of the permeable cement concrete as the design parameters, the effective porosity concept was used to compare the raw material specifications with the gradation, water-cement ratio and cement slurry, and analyzed the relationship between effective porosity and permeability coefficient. This relationship is recommended for the mix of recycled permeable concrete on the haze removal pavement.
