Additives were added to pervious concrete pavement to improve the removal capacity for runoff contaminants. In this study, static isothermal adsorption experiments were conducted for concrete prepared with fly ash or bentonite. The results showed that the material containing bentonite showed better adsorption capacity for runoff contaminants. The saturated adsorption values of bentonite for major runoff pollutants, including chemical oxygen demand (COD), total phosphorus (TP) and copper (Cu) were 8.61, 6.93, 19.31 mg/g respectively. However, the two additives showed only weak adsorption capacity for total nitrogen (TN). Compared to hardened cement, the adsorption capacity for COD, TP and Cu of the cement with bentonite was increased by 54%, 30% and 42% respectively, and the capacity of cement with fly ash increased by 42%, 11% and 33% respectively. Therefore, additives can improve the decontamination capacity of the base layer of the pervious concrete pavement. This study provides technical support for the construction of a sponge city.

Abstract


Additives were added to pervious concrete pavement to improve the removal capacity for runoff contaminants. In this study, static isothermal adsorption experiments were conducted for concrete prepared with fly ash or bentonite. The results showed that the material containing bentonite showed better adsorption capacity for runoff contaminants. The saturated adsorption values of bentonite for major runoff pollutants, including chemical oxygen demand (COD), total phosphorus (TP) and copper (Cu) were 8.61, 6.93, 19.31 mg/g respectively. However, the two additives showed only weak adsorption capacity for total nitrogen (TN). Compared to hardened cement, the adsorption capacity for COD, TP and Cu of the cement with bentonite was increased by 54%, 30% and 42% respectively, and the capacity of cement with fly ash increased by 42%, 11% and 33% respectively. Therefore, additives can improve the decontamination capacity of the base layer of the pervious concrete pavement. This study provides technical support for the construction of a sponge city.
