HighlightsInvestigation of hydraulic conductivity of pervious concrete.Proposing a relationship between hydraulic conductivity and pore tortuosity.Defining pore tortuosity by the relative mean pore size.Incorporation of the proposed relationship into the Kozeny-Carman model.
AbstractA variety of empirical models have been proposed by other researchers correlating hydraulic conductivity to effective porosity for pervious concrete (PC). However, most of these models do not account for the influence of pore tortuosity or require complicated measurements. To quantify the influence of pore tortuosity, PC with different microstructure is proportioned through varying workability of matrix, amount of binder and size of aggregate. A relationship between relative mean pore size and pore tortuosity is proposed and incorporated into the Kozeny-Carman model. The relative mean pore size is defined as the ratio of mean pore size to aggregate size. Mean pore size is derived from the pore size distribution (PSD) extracted from linear path function (LPF) tailored to PC. The modified Kozeny-Carman model is validated by the agreement between predicted and experimentally obtained results.
