NettetOsmosis is the diffusion of water molecules, from a region where the water molecules are in higher concentration, to a region where they are in lower concentration, through a partially permeable ... NettetHence, concrete would be permeable when free water leaves the pores due to evaporation or any other reason. Fig.1 explains the relationship between water to cement ratio and concrete permeability. Typically, at a water cement ratio of around 0.4, permeability is practically nil.
