Neue Methoden zur Auswertung von Sw-ρ-Beziehungen

ABSTRACT: The electrical resistivity of concrete is often used to make statements about the durability of reinforced concrete structures. The aim of the presented investigations is to characterise water content-resistivity relationships as a function of relevant structural parameters of the concrete. For this purpose, an approach based on Archie's law was chosen, the results of which are presented and compared with the commonly used model. An attempt is made to cone selected parameters with the properties of the pore system of the concretes and thus to demonstrate the possibilities of the presented approach.
