Abstract:
The fundamental material characteristic that makes pervious concrete a sustainable material is its open pore structure. Characterization of the pore structure thus becomes important in the evaluation and prediction of pervious concrete performance. This article provides details on methods for characterizing pore structure features such as porosity, pore size, and pore connectivity and how to use these features to predict the performance of pervious concrete.
