摘要：

In this study, the performance of pervious concrete in improving runoff quality is investigated.Limestone powder was employed as a substitute for cement to evaluate the replacement of this material to improve the quality of the runoff. COD (chemical oxygen demand), BOD (biological oxygen demand), EC (electrical conductivity), TSS (total suspended solids), and turbidity tests are all part of environmental runoff tests. Runoff from plain pervious concrete (PPC) and pervious concrete containing 15% limestone powder were used to determine the efficacy of removing each of these pollutants (PCL15). In all cases, the results showed that PCL15 was more efficient than PPC at removing pollutants. It was found that the PCL15's highest removal efficiency was 72 percent, which is related to turbidity. The statistical analysis of pollution removal efficiency in PPC and PCL15 runoff showed a significant difference between these averages.
