Virtual Pervious Concrete: Microstructure, Percolation, and Permeability

As the dramatic increase in pervious concrete usage continues, a better understanding of microstructure, durability, and transport property linkages will assist suppliers with mixture design and properties. Various virtual pervious concrete microstructural models are presented in this paper, and their computed transport properties and percolation characteristics are compared to real world pervious concretes. Of the various virtual pervious concretes the study explores, a correlation filter three-dimensional reconstruction algorithm-based one clearly provided a void structure closest to what is achieved in real pervious concretes. Durability issue extensions, such as clogging and freezing-and-thawing persistance, that use further virtual pervious concrete void structure analysis are introduced.
