The pervious cement concrete (PC) or Permeable concrete is a special type of concrete with no or little sand, which exhibited an excellent hydrological function in decreasing the water runoff. However, accurate prediction of its water permeability coefficient using the Constant Head Method (CHM) is still unreliable due to the previous models have been established using a small size of PC samples, also these models have not been evaluated so far to understand its behavior in a large database. Thus, the authors think that the convenient time to propose a reliable model to predict the water permeability of PC, especially in the existence of large experimental PC Samples in literature. In this study, the experimental data of PC from (2016–2021) that was conducted in the previous work has been collected to build a database of the PC samples, which calculated the permeability coefficient using CHM. This effort provides …
