Discussion of 'A new suction method for the measurement of pore size distribution of filter layer in permeable formwork' by Zhenghong Tian, Xiaodong Wang and Xudong Chen

摘要

A water suction method for determining the pore size distribution of permeable framework in the form of nonwoven material has been developed in the original work. The authors have also theoretically calculated the pore size distribution of nonwoven materials using existing theories. There are technical issues that need to be addressed before applying such an experimental technique for determining the pore size distribution of nonwoven materials. The prediction of pore size distribution of nonwoven materials require correct measurement of input parameters otherwise, the model can easily yield overestimations, as evident in the discussed publication.
