However, several experimental investigations have indicated that concrete permeability both with respect to air and to water is an excellent measure for the resistance of concrete against the ingress of aggressive media in the gaseous or in the liquid satet and thus is a measure of the potential durability of a particular concrete."
Sin embargo, diversas investigaciones han indicado que la permeabilidad del hormigón, al aire o al agua, es una excelente medida de su resistencia al ingreso de medios agresivos en el estado gaseoso o líquido y así constituye una medida de la durabilidad potencial de un hormigón dado."
