Virtual Pervious Concrete: Microstructure, Porosity Percolation, and Permeability Prediction

Abstract

As the usage of pervious concrete continues to increase dramatically, a better understanding of the linkages between microstructure, transport properties, and durability will assist suppliers in mixture proportioning and design. This paper presents various virtual pervious concrete microstructural models and compares their percolation characteristics and computed transport properties to those of real world pervious concretes. Of the various virtual pervious concretes explored in this study, one based on a correlation filter three-dimensional reconstruction algorithm clearly provides a void structure closest to that achieved in real pervious concretes. Extensions to durability issues, such as freeze-thaw resistance and clogging, that utilize further analysis of the virtual pervious concrete s void structure are introduced.
